Аннотация: Optical properties of 2D nanocomposite-based photonic crystals with a lattice defect are studied. The nanocomposite comprises metallic nanospheres dispersed in a transparent matrix and is characterized by an effective resonant permittivity. Transmission spectrum for s-polarized waves at oblique incidence is calculated. Spectral manifestation of the splitting of the defect mode when its frequency coincides with the resonant frequency of the nanocomposite is studied. The essential dependence of the splitting on the angle of incidence and concentration of metallic nanospheres in the nanocomposite matrix is established. Specific features of spatial distribution of the electric field intensity in defect modes of crystals are analyzed.

Аннотация: We have studied the transmission spectra of resonant two-dimensional photonic crystals of two types, one of which consists of nanocomposite cylinders that form a square lattice in vacuum and the other of which consists of cylindrical holes that form a square lattice in nanocomposite matrix. The nanocomposite consists of metallic nanospheres that are dispersed in a transparent matrix and is characterized by an effective resonant dielectric permittivity. We show that, depending on the position of the resonant frequency of the nanocomposite with respect to the boundaries of the band gap, there arises either an additional transmission band in the transmission spectrum in the band gap or an additional band gap in the continuous spectrum of the photonic crystal. As the structural and geometric parameters of the system change, both the additional transmission band and the additional band gap are considerably modified. We analyze particular features of the spatial distribution of the electromagnetic field intensity in crystals. The considered effects can be used to extend the possibilities of creating new photonic crystals with specified properties.

Аннотация: The band structure of two-dimensional resonant photonic crystals of two types has been calculated using the expansion of eigenfunctions in plane waves. Crystals of one type consist of infinite dielectric cylinders forming a square lattice filled with a resonant gas, and crystals of the other type consist of infinite cylindrical holes filled with a resonant gas and forming a square lattice in a dielectric matrix. It has been shown that, in both cases, the dispersion of a resonant gas in combination with the dispersion of a two-dimensional structure with a photonic band gap leads to the appearance of an additional narrow transmission band near the edge of the band gap or an additional band gap in the continuous spectrum of the photonic crystal. The calculations performed have demonstrated that new dispersion properties substantially depend on the density of the resonant gas, the position of the resonant frequency with respect to the edge of the band gap, and the direction of propagation of electromagnetic waves.

Аннотация: The transmission spectra of two-dimensional resonant photonic crystals of two types have been investigated. Crystals of one type consist of dielectric cylinders forming a square lattice filled by a resonant gas with mercury atoms, and crystals of the other type consist of cylindrical holes filled with a gas and forming a square lattice in a dielectric matrix. It has been established that characteristics of the spectrum of additional transmission arising in the band gap of the photonic crystal can be changed significantly by varying the gas pressure and the angle of incidence. It has been demonstrated that the calculated features in the transmission spectrum of the photonic crystal are stable with respect to a significant increase in the width of the atomic resonance.

Аннотация: The model of a polarization-preserving anisotropic mirror is proposed. The mirror is a plane boundary of a metal–dielectric nanocomposite that consists of silver spheroidal nanoparticles dispersed in a transparent matrix. The dependence of reflection spectra on the shape of the nanoparticles is studied. It is shown that in one region of the spectrum, the mirror preserves the sign of polarization in the reflected light. © 2017, Allerton Press, Inc.

High-Q nodes-free mode for lasing / N. V. Rudakova [et al.] // Progress in Electromagnetics Research Symposium : Abstracts. - 2018. - P. 2013. - Cited References: 3
Аннотация: Discrete-chiral medium [1] is a set of slab-sided layers of anisotropic material with optical axis constantly rotating layer by layer. Right-angled rotation produces an alternation of vertically and horizontally oriented layers (Fig. 1(a), inset). The structure transforms from chiral to non-chiral (ambichiral) one. On the one hand, the discrete-ambichiral medium possesses a polarisation-independent stopband, similar to multilayer mirror made of isotropic materials. On the other hand, similar to continuous-chiral medium, like cholesteric liquid crystal or chiral sculptured thin ﬁlm, the reﬂected light has the same sign of circular polarization as the incident light. On the basis of such chiral mirrors the ideas of nodes-free laser [2] and surface light localization [3] were proposed. In this study a new high-quality nodes-free mode in all-dielectric structure is examined for eﬃcient lasing. The reason for removed nodes and antinodes (Fig. 1(a)) is the suppressed interference for orthogonally polarized oppositely running waves [2]. The nodes-free standing wave in the laser active layer is advantageous in spacially homogeneous pumping and consequent growth of eﬃcient and stability. Another opportunity is that the in-plane rotation of one mirror by ϕ changes the Pancharatnam Berry phase by 2ϕ and smoothly shifts the mode frequency (Fig. 1(b)). Clockwise rotation shifts the right circularly polarized eigenmodes to shorter wavelengths and left circularly polarized ones to longer wavelengths.

Cholesteric liquid crystal -- Optical Tamm states -- Localization -- Transmission spectrum -- Optical devices
Аннотация: The modes formed by two coupled chiral optical Tamm states localized at the interfaces between a photonic cholesteric liquid crystal conjugated with polarization-preserving anisotropic mirrors have been analytically and numerically investigated. These modes are only excited at the diffracting polarization of incident light. As the cholesteric layer thickness decreases, the spectral splitting of the localized state frequency is predicted. The splitting value depends on the crystal layer thickness. At the nondiffracting circular polarization, the localized modes are not excited, and the system becomes similar to the Fabry-Perot cavity containing an anisotropic helical structure.

Аннотация: The structure consisting of alternating uniaxial dielectric layers is known to produce reflection of the same polarization as the incident field; e.g., the right-hand elliptically polarized light preserves this right-handedness and ellipticity of polarization at reflection. The parameters permitting the properly-polarized reflectance to exceed 99% in a wide frequency range were considered both analytically and numerically. The mirror with tuned top-layer thickness is shown to have several times less polarization losses than the uniform mirror. The hybrid mirror with metallic bottom layer has a considerably reduced thickness.
