“…The nanoparticles in our study, as in [7], were assumed to be made of gold, which is one of the most widespread materials for plasmonics. The electron damping coefficient in the Drude-Sommerfeld model for gold differs from that for silver (used in [3][4][5][6]) by an order of magnitude.…”

“…New techniques for controlling light can be implemented using a defect layer in a one-dimensional PC in the form of an isotropic nanocomposite layer consisting of spherical metal nanoparticles dispersed in a transparent matrix [3][4][5][6]. SiO 2 -and TiО 2 -based nanocomposite films containing spherical gold nanoparticles were fabricated and investigated (both experimentally and theoretically) in [7].…”

The spectral properties of a one-dimensional photonic crystal (PC) with a structure defect (a layer of isotropic nanocomposite inserted between two multilayer dielectric mirrors) have been investigated. The nanocomposite consists of spherical gold nanoparticles dispersed in a transparent matrix; it is characterized by effective resonant permittivity. The dependence of the transmission and absorption spectra on the size and concentration of nanoparticles is analyzed. It is shown that the transmission spectrum contains, along with the band gap caused by Bragg diffraction of light, an additional nontransmission band due to the nanocomposite absorption near the resonant frequency.

“…The use of metal-dielectric nanocomposites as the media in the composition of photonic crystal structures leads to the manifestation of such effects as the appearance of an additional photonic band gap, splitting of the transmission regions in the photonic band gaps of defective photonic crystals, and the polarization sensitivity of the spectra of photonic crystals (Moiseev et al 2012;Vetrov et al 2011Vetrov et al , 2014.…”

“…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.
