“…A nanocomposite is a dielectric matrix with metallic particles uniformly distributed over its volume, which is characterized by the resonant effective permittivity. The optical properties of initial materials have no resonant features [15][16][17]. The position of a resonance in the visible spectral range, as well as the frequency band where the NC behaves like a metal are determined by the effective permittivity.…”

Two schemes of excitation of a Tamm plasmon polariton localized at the interface between a photonic crystal and a nanocomposite with near-zero effective permittivity have been investigated in the framework of the temporal coupled-mode theory. The parameters of the structure have been determined, which correspond to the critical coupling of the incident field with a Tamm plasmon polariton and, consequently, ensure the total absorption of the incident radiation by the structure. It has been established that the spectral width of the absorption line depends on the scheme of Tamm plasmon polariton excitation and the parameters of a nanocomposite film. The features of field localization at the Tamm plasmon polariton frequency for different excitation schemes have been examined. It has been demonstrated that such media can be used as narrowband absorbers based on Tamm plasmon polaritons localized at the interface between a photonic crystal and a nanocomposite with near-zero effective permittivity.

“…Apart from various practical implementations of Fabry-Pérot cavities, 1D photonic crystal (PhC) with defect layer represents a case of specific interest due to non-trivial coupling of NPs with PhC defect modes. The latter phenomenon may yield in improved performance of surface-enhanced Raman spectroscopy [10], ultrafast light modulation [11], PhC mode splitting [12,13], and controllable discretization of NPs optical absorption [14].…”

We analytically and numerically study coupling mechanisms between 1D photonic crystal (PhC) and 2D array of plasmonic nanoparticles (NPs) embedded in its defect layer. We introduce general formalism to explain and predict the emergence of PhC-mediated Wood-Rayleigh anomalies, which spectral positions agree well with the results of exact simulations with Finite-Difference Time-Domain (FDTD) method. Electromagnetic coupling between localized surface plasmon resonance (LSPR) and PhC-mediated Wood-Rayleigh anomalies makes it possible to efficiently tailor PhC modes. The understanding of coupling mechanisms in such hybrid system paves a way for optimal design of sensors, light absorbers, modulators and other types of modern photonic devices with controllable optical properties.

“…The studies on spectral properties of a one-dimensional PC with defect nanocomposite layers containing nano-sized metal inclusions of spherical [14,15] or spheroidal orientationally ordered shape [16] have been conducted. This paper is dedicated to a study of the peculiarities of spectral properties of the one-dimensional PC with a resonant absorbing defect layer of the nanocomposite, which consists of spheroidal silver nanoparticles orientationally ordered in a dielectric matrix.…”

We have studied the spectral properties of a one-dimensional photonic crystal with a structure defect that represents an anisotropic nanocomposite layer sandwiched between two multilayer dielectric mirrors. The nanocomposite consists of metallic nanoscale inclusions of orientationally ordered spheroidal shape, dispersed in a transparent matrix, and is characterised by an effective resonant permittivity. Each of the two orthogonal polarisations of probe radiation corresponds to a particular plasmon resonant frequency of the nanocomposite. The problem of calculating the transmittance spectrum of the waves with s-and p-polarisations for such structures is solved. Spectral manifestation of splitting of the defect mode depending on the structure parameters and volumetric fraction of the nanospheroids is studied. The essential dependence of the position of maxima of the defect modes in the bandgap of the photonic crystal and their splitting on the incidence angle, polarisation, and the ratio of lengths of the polar and equatorial semi-axes of the spheroidal nanoparticles is shown.
