    Abstract:
    We report the suppression of loss of surface plasmon polariton propagating at the interface between silver film and optically pumped polymer with dye. Large magnitude of the effect enables a variety of applications of ‘active’ nanoplasmonics. The experimental study is accompanied by the development of the analytical description of the phenomenon and the solution of the controversy regarding the direction of the wavevector of a wave with a strong evanescent component in an active medium.

    Abstract:
    We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics – parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique and its possible applications for sensing and imaging structures, high-performance mode couplers, optical cloaking structures, and dynamically reconfigurable electro-plasmonic circuits.

    [pdf/ arXiv/ abstract]
    Abstract:
    We resolve the long-standing controversy regarding far-field imaging by a planar lens made of a left-handed medium and demonstrate theoretically that the far-field image has a fundamentally different origin depending on the relationship between losses inside the lens and the wavelength of the light, l. At small enough l, the image is always governed by diffraction theory, and the resolution is independent of the absorption if both Im[e]<<1 and Im[m]<<1. For any finite l, however, a critical absorption exists below which the superresolution regime occurs, although this absorption is extremely low and can hardly be achieved. We demonstrate that the transition between the diffraction-limited and superresolution regimes is governed by a universal parameter combining absorption, wavelength, and lens thickness. Finally, we show that this parameter is related to the resonant excitation of surface plasma waves.

    [pdf/ arXiv/ abstract]
    Abstract:
    We derive an approach to define the causal direction of the wavevector of modes in optical metamaterials, which in turn, determines signs of refractive index and impedance as a function of real and imaginary parts of dielectric permittivity and magnetic permeability. We use the developed technique to demonstrate that the interplay between resonant response of constituents of metamaterials can be used to achieve efficient dispersion management. Finally we demonstrate broadband dispersion-less index and impedance matching in active nanowire-based negative index materials. Our work opens new practical applications of negative index composites for broadband lensing, imaging, and pulse-routing

    [url/ first paragraph]
    Abstract:
    An optical metamaterial is a composite in which subwavelength features, rather than the constituent materials, control the macroscopic electromagnetic properties of the material. Recently, properly designed metamaterials have garnered much interest because of their unusual interaction with electromagnetic waves1–3. Whereas nature seems to have limits on the type of materials that exist, newly invented metamaterials are not bound by such constraints. These newly accessible electromagnetic properties make these materials an excellent platform for demonstrating unusual optical phenomena and unique applications such as subwavelength imaging and planar lens design. ‘Negative-index materials’, as first proposed, required the permittivity, ", and permeability, μ, to be simultaneously less than zero, but such materials face limitations. Here, we demonstrate a comparatively lowloss, three-dimensional, all-semiconductor metamaterial that exhibits negative refraction for all incidence angles in the long-wave infrared region and requires only an anisotropic dielectric function with a single resonance. Using reflection and transmission measurements and a comprehensive model of the material, we demonstrate that our material exhibits negative refraction. This is furthermore confirmed through a straightforward beam optics experiment. This work will influence future metamaterial designs and their incorporation into optical semiconductor devices.

    Abstract:
    We show that a stack of metal-dielectric nanolayers, in addition to the long- and short-range plasmon polaritons, guides also an entire family of modes strongly confined within the multilayer – the bulk plasmon polariton modes. We propose a classification scheme that reflects specific properties of these modes. We report experimental verification of the bulk modes by measuring modal indices in a structure made of three pairs of silica(~29nm)/gold(~25nm) layers

    Abstract:

Applying basic dispersion engineering principles to model a broadband and large reflectance asymmetry, we obtain a model dielectric function for the metamaterial film, closely resembling the effective permittivity of disordered metal-dielectric nano-composites. Coatings realized using disordered nanocrystalline silver films deposited on glass substrates confirm the theoretical predictions, exhibiting symmetric transmittance, large reflectance asymmetries and a unique flat reflectance asymmetry.

We develop the analytical description of the relevant phenomena and confirm our results with numerical solutions of Maxwell equations.

    Abstract:
    Classical counterparts of a great variety of quantum systems, from atomic physics to quantum wells and quantum dots, to optical, microwave, and acoustic resonators exhibit partially chaotic dynamics. Since it is often impossible to measure the temporal dynamics in qunatum systems, the main and probably the most dramatic manifestation of classical chaos in their phase space is seen in the distribution of spacing between the neighboring energy levels. While the mechanism leading to the onset of chaotic dynamics is different in every system, the level spacing distribution obeys the universal law, changing from Poissonian in the completely integrable systems to Wigner in completely chaotic ones

    [pdf/ press release/ arXiv/ abstract]
    Abstract:
    We study the energy propagation in subwavelength waveguides and demonstrate that the mechanism of material gain, previously suggested for loss compensation, is also a powerful tool to manipulate dispersion and propagation characteristics of electromagnetic pulses at the nanoscale. We show theoretically that the group velocity in lossy nano-waveguides can be controlled from slow to superluminal values by the material gain and waveguide geometry and develop an analytical description of the relevant physics. We utilize the developed formalism to show that gain-assisted dispersion management can be used to control the transition between ``photonic-funnel'' and ``photonic-compressor'' regimes in tapered nano-waveguides. The phenomenon of strong modulation of group velocity in subwavelength structures can be realized in waveguides with different geometries, and is present for both volume and surface-modes.

    Abstract:
    We study the perspectives of nanowire-based metamaterials for negative-refraction waveguides, high-performance polarizers, and polarization-sensitive biosensors. We demonstrate that the behavior of these composites is strongly influenced by the concentration, distribution, and geometry of the nanowires . We derive analytical description of electromagnetism in anisotropic nanowire-based metamaterials and show that it is possible to use nanowire systems to achieve an extreme anisotropy of the dielectric constant required for high energy-density waveguides and non-magnetic negative index systems. Finally, we study the limitations of our analytical results via 3D numerical solutions of Maxwell equations.

    Abstract:
    We present waveguides with photonic crystal cores, supporting energy propagation in subwavelength regions with a mode structure identical to that in telecom fibers and develop analytical description of light transmission through these systems. We design meta-materials for near-, mid-, and far-IR frequencies, and demonstrate ~10...30% energy transfer to and from regions smaller than 1/25-th of the wavelength via numerical solution of Maxwell equations. Both positive- and negative-refractive index light transmissions are shown. Our approach, although demonstrated here in circular waveguides for some specific frequencies, is easily scalable from optical to IR to THz frequency ranges, and can be realized in a variety of waveguide geometries. Our design may be used for ultra high-density energy focusing, nm-resolution sensing, near-field microscopy, and high-speed photonic computing.

    [url/ arXiv/ abstract]
    Abstract:
    We develop an approach to use nanostructured plasmonic materials as a non-magnetic negative-refractive index system at optical and near-infrared frequencies. In contrast to conventional negative refraction materials, our design does not require periodicity and thus is highly tolerant to fabrication defects. Moreover, since the proposed materials are intrinsically non-magnetic, their performance is not limited to proximity of a resonance so that the resulting structure has relatively low loss. We develop the analytical description of the relevant electromagnetic phenomena and justify our analytic results via numerical solutions of Maxwell equations.

    Abstract:
    We report the demonstration of surface-plasmon microcylinder quantum cascade lasers with circular and deformed resonators. An improved self-alignment fabrication technique was developed that allows the use of wet etching, necessary to achieve smooth and clean surfaces, in combination with the deposition of the surface-plasmon-carrying metal layer up to the very edge of the resonator, where the optical mode is mostly located. The diameter of the microcylinders ranges from 75 to 180 /spl mu/m while their deformation coefficient /spl epsiv/ ranges from /spl epsiv/=0 to /spl epsiv/=0.32. Circular microcylinder lasers show a reduction of /spl sim/50% of the threshold current density with respect to devices with standard ridge-waveguide resonators. On the other hand, highly deformed microcylinder lasers exhibit a complex mode structure, suggesting the onset of chaotic behavior.

    [pdf/ url/ press release/arXiv/ abstract]
    Abstract:
    We analyze the performance of a planar lens based on realistic negative index material in a generalized geometry. We demonstrate that the conventional superlens design (where the lens is centered between the object and the image) is not optimal from the resolution point-of-view, develop an analytical expression for the resolution limit of a generalized lens, use it to find the optimum lens configuration, and calculate the maximum absorption practical nearfield superlenses may have. We demonstrate that in contrast to the conventional superlens picture, planar imaging is typically accompanied by excitation of surface waves at both interfaces of the lens.

    [ url/ abstract ]
    Abstract:
    Enlarging upon work of Nicorovici, McPhedran, and Milton (1994) a rigorous proof is given that in the quasistatic regime a cylindrical superlens can successfully image a dipolar line source in the limit as the loss in the lens tends to zero. In this limit it is proved that the field blows up to infinity in two sometimes overlap- ping annular anomalously locally resonant regions, one of which extends inside the lens and the other of which extends outside the lens. If the object being imaged responds to an applied field it is argued that it must lie outside the resonant re- gions to be successfully imaged. If the image is being probed it is argued that the resonant regions created by the probe should not interfere with either the probe itself or the object being imaged, if that object responds to an applied field. Per- fect imaging in a cylindrical superlens is shown to extend to the static equations of magnetoelectricity or thermoelectricity provided they have a special structure which makes these equations equivalent to the quasistatic equations.

    Abstract:
    We demonstrate the lasing action from a dynamically localized mode in a microdisk resonator with rough boundary. Although substantial boundary roughness and surface defects in our devices imply strong light scattering and destroy the regular whispering gallery modes, the destructive interference of the scattered light leads to the dynamical Anderson localization in the phase space of the system and the formation of a different type of high-Q modes. Using direct optical imaging of the lasing mode and theoretical calculations, we show that the lasing modes in our devices has dynamical localization origin. This behavior, although demonstrated here in GaAs-InAs microdisk laser, should be applicable to any lasers and sensors based on semiconductor or polymer materials

    Abstract:
    We develop an approach to build a material with negative refraction index that can be implemented for optical and infrared frequencies. In contrast to conventional designs that require simultaneously negative dielectric permittivity and magnetic permeability and rely on a resonance to achieve a nonzero magnetic response, our material is intrinsically nonmagnetic and makes use of an anisotropic dielectric constant to provide a lefthanded behavior in waveguide geometry. We demonstrate that the proposed material can support surface (polariton) waves, and show the connection between the polaritons and the enhancement of evanescent fields, also known as superlensing.

We also show that both dielectric permittivity and magnetic permeability can be negative at optical and near infrared frequencies, and demonstrate the connection between the geometry of the system and its resonance characteristics. We conclude that plasmonic nanowires can be employed for developing novel negative-index materials. Finally, we demonstrate that it is possible to construct a nanowire-based "transparent nanoresonator&" with dramatically enhanced intensity and metal concentration below 5%

    Abstract:
    The materials with simultaneously negative dielectric permittivity and magnetic permeability also known as left-handed materials (LHMs), are among the most rapid-developing topics in the modern scientific community due to their exciting and often unnatural electromagnetic properties. The ``ultimate application'' of LHM is the construction of a lens with ``perfect'' (subwavelength) optical resolution in the far field, which -- although potentially leading to a tremendous advance in imaging, fabrication, and communications -- have initiated a lot of controversy. In the present work we show that the LHM-based lens ceases to be perfect in the presence of even a small absorption and the area of its subwavelength resolution is usually limited to the proximity of the scatterer, similarly to well-developed near-field optics. We derive the relation between the focal distance and resolution of the superlens, and resolve the above mentioned controversy

    Abstract:
    We report the first direct observation of lasing action from a dynamically localized mode in a microdisk resonator with rough boundary. In contrast to microlasers based on stable ray trajectories, the performance of our device is robust with respect to the boundary roughness and corresponding ray chaos, taking advantage of Anderson localization in angular momentum. The resonator design, although demonstrated here in GaAs-InAs microdisk laser, should be applicable to any lasers and sensors based on semiconductor or polymer materials.

    [ pdf / abstract ]

    Abstract:
    Hashiguchi has studied the limitedness problem of distance automata (DA) in a series of paper [(J. Comput. System Sci. 24 (1982) 233; Theoret. Comput. Sci. 72 (1990) 27; Theoret. Comput. Sci. 233 (2000) 19)]. The distance of a DA can be limited or unbounded. Given that the distance of a DA is limited, Hashiguchi has proved in Hashiguchi (2000) that the distance of the automaton is bounded by 24n3+n lg(n+2)+n, where n is the number of states. In this paper, we study again Hashiguchi’s solution to the limitedness problem. We have made a number of simpli=cation and improvement on Hashiguchi’s method. We are able to improve the upper bound to 23n3+n lg n+n-1.

    Abstract:
    We study tunneling between regular and chaotic regions in the phase space of Hamiltonian systems. We analytically calculate the transition rate and show that its variation depends only on corresponding phase space area and in this sense is universal.We derive the distribution of level splittings associated with the pairs of quasidegenerate regular eigenstates which in the general case is different from a Cauchy distribution. We show that chaos-assisted tunneling leads to level repulsion between regular eigenstates, solving the longstanding problem of level-spacing distribution in mixed systems.

    [ pdf / abstract ]

    Abstract:
    Optical properties of metal nanowires and nanowire composite materials are studied. An incident electromagnetic wave can effectively couple to the propagating surface plasmon polariton (SPP) modes in metal nanowires resulting in very large local fields. The excited SPP modes depend on the structure of nanowires and their orientation with respect to incident radiation. A nanowire percolation composite is shown to have a broadband spectrum of localized plasmon modes. We also show that a composite of nanowires arranged into parallel pairs can act as a left-handed material with the effective magnetic permeability and dielectric permittivity both negative in the visible and near-infrared spectral ranges.

    Abstract:
    The electromagnetic field distribution for thin metal nanowires is found, by using the discrete dipole approximation. The plasmon polariton modes in wires are numerically simulated. These modes are found to be dependent on the incident light wavelength and direction of propagation. The existence of localized plasmon modes and strong local field enhancement in percolation nanowire composites is demonstrated. Novel left-handed materials in the near-infrared and visible are proposed based on nanowire composites.

    [ pdf/ abstract ]

    Abstract:
    In metal–dielectric percolation films, plasmon modes are localized in nm-sized areas, “hot-spots,” where EM-field is extremely enhanced. When the excitation pulse has a broad spectrum, sub-femtosecond opti- cal responses can occur locally on such films. Thus, sub-wavelength spatial localization and sub-light-period time localization are both possible in metal–dilectric percolation films.

    [ pdf / abstract ]

    Abstract:
    An analytical theory for extraordinary light trans-mittance through an optically thick metal film with subwavelength holes is developed. It is shown that the film transmittance has sharp peaks that are due to the Maxwell–Garnet resonances in the holes. There are localized electric and magnetic resonances resulting in, respectively, dramatically enhanced electric and magnetic fields in the holes. A simple analytical expression for the resonance trans-mittance is derived that holds for arbitrary hole distribution. It is also shown that there are other types of transmittance resonances, when the holes are arranged into a regular lattice. These reso-nances occur because of the excitation of surface plasmon polari-tons propagating over the film surface. A combination of the two kinds of resonances results in a rich spectral behavior in the extra-ordinary optical transmittance.

    [ pdf / abstract ]

    Abstract:
    A novel class of composites for optics, microcavities doped with metal fractal aggregates, is studied. Lasing and broad-band Stokes and anti-Stokes emission from (Ag colloidal aggregates)/(adsorbed molecules)/(micro-cavity) composite at low-intensity cw and pulse laser excitation has been found. At 633 nm cw excitation wavelength the emission spectrum contains many peaks, spanning a range from wavelength 200 nm to 800 nm. Experiments with pulse excitation of Ag/dye/microcavity composite show that the duration of the observed broad-band anti-Stokes emission significantly exceeds the pump pulse duration, dye molecule fluorescence time, and relaxation times in silver particles. It may be interpreted as a luminescence governed by long-living triplet states of dye molecules. These observations were made possible by use of a fractal-microcavity composite, where coupling the localized plasmon modes in fractal aggregates with microcavity resonances is provided. The important role of multiphoton resonant transitions between discrete states of a finite-size metal particle in enhanced local fields is shown. Analysis, based on the model of a spherical potential well, shows that the observed spectra contain fingerprints of the quantum size effect.

    [ pdf / abstract ]

    Abstract:
    Large local optical activity in fractal aggregates of silver nanoparticles has been observed by means of photon scanning tunneling microscopy. The effect occurs because resonant plasmon modes in random fractals can have handedness in spatial distribution of their amplitudes. In agreement with experimental observations, numerical simulations show dramatic difference in dipole-moment distributions for right- and left-circularly polarized incident light when the cluster size is comparable with or larger than the wavelength. Variations in the local parameter describing the circular intensity difference of scattered light show that fractal aggregates are characterized by broad and random distributions of chiral plasmon modes. © 2001 Optical Society of America

    [ pdf / abstract ]

    Abstract:
    Local field distributions in random metal-dielectric films near a percolation threshold are experimentally studied using scanning near-field optical microscopy ~SNOM!. The surface-plasmon oscillations in such per-colation films are localized in small nanometer-scale areas, ‘‘hot spots,’’ where the local fields are much larger than the field of an incident electromagnetic wave. The spatial positions of the hot spots vary with the wavelength and polarization of the incident beam. Local near-field spectroscopy of the hot spots is performed using our SNOM. It is shown that the resonance quality-factor of hot spots increases from the visible to the infrared. Giant local optical activity associated with chiral plasmon modes has been obtained. The hot spot’s large local fields may result in local, frequency and spatially selective photomodification of percolation films.

    [ pdf / abstract ]

    Abstract:
    Strongly enhanced second-harmonic generation ~SHG!, which is characterized by a nearly isotropic intensity distribution, is observed for gold-glass films near the percolation threshold. The diffuselike SHG scattering, which can be thought of as nonlinear critical opalescence, is in sharp contrast with highly collimated linear reflection and transmission from these nanostructured semicontinuous metal films. Our observations, which can be explained by giant fluctuations of local nonlinear sources for SHG due to plasmon localization, verify recent predictions of percolation-enhanced nonlinear scattering.

    Abstract:
    It is shown that in cerments, with metal percolating clusters in a dielectric host, the metal plasmon modes cn strongly couple to the dielectric vibrational modes, optical phonons. In metal-dielectric percolation composites, the pasmon modes are capable of strong addumulation of the electromagnetic energy in small nanometer-sized areas, "hot-spots". The local fields in the hot spots can be very large, leading to enhanced absorption by optical phonons of the dielectric. In our experiments, strongly enhanced absorption by the coupled plasmon-phonon modes has been observed in Au-Al2O3 percolation composites.

    Abstract:
    Optical properties of fractal nanostructured composite materials are considered. The fractal geom-etry results in localization of plasmon excitations in the “hot” spots, where the local field can exceed the applied field by several orders of magnitude. The high local fields of the localized fractal modes result in dramatic enhancement of optical responses, making feasible the surface-enhanced nonlinear spectroscopy of single mol-ecules and nanocrystals. The field enhancement becomes especially large when fractals are placed inside a microcavity. A theory for the enhanced Raman and hyper-Raman surface-enhanced scattering in microcavity– fractal composites is developed.

    Abstract:
    We present detailed description of a computer method for the calculation of the conductivity of inhomogeneous systems based on an exact renormalization group transformation. We study by this method the effective conductivity of the three-dimensional resistor network at the percolation threshold. For lattices ranging in size from 43 to 1403 we measure the dissipation, finding t/vp=2.305(15), where t is the conductivity exponent and vp is the correlation length exponent.

    Abstract:
    Local field distributions are studied in random metal-dielectric films near percolation (percolation films) and fractal aggregates of colloidal particles. For both systems, it is shown that optical excitations are localized in small nanometer-sized areas, "hot spots," where the local fields are much larger than the field of an incident electromagnetic wave. The large local fields result in giant enhancement of various optical phenomena. The surface-enhanced white-light generation and second-harmonic generation have been obtained in percolation films. For fractal aggregates of silver particles, a giant effect of local optical activity has been observed. The effect is due to surface-plasmon excitations localized on chiral-active particle configurations in fractals

    Abstract:
    Optical properties of metal nanowires and nanowire composite materials are studied experimentally and theoretically. We suggest that a nanowire composite, constructed from parallel pairs of nanowires has both effective magnetic permeability and dielectric permittivity negative in the visible and near-infrared spectral ranges due to resonant excitation of surface plasmon polaritons. Experimental results confirm excitation of surface plasmons polaritons in periodical array of nanowires.

    [ pdf / abstract ]

    Abstract:
    Dielectric spheres and cylinders can support high-Q modes due to internal reflection of the light. However, small deviations of the shape of these resonators away from symmetry lead to the onset of chaotic ray dynamics and the resulting suppression of the mode lifetimes. We demonstrate, that in such conditions even the regular modes are strongly affected by small deformations, due to the phenomenon of chaos-assisted tunneling, and develop a quantitative theory of this effect.
