“…Since the modifi cation of the spectra of these hybrids cannot be described by the linear superposition of individual properties of their components, they fall under the defi nition of resonance PhCs. [ 11 ] First of all, in the PBG spectral range of the 2D slab PhC ( D/ λ ≈ 0.9), the overall transmission of the silver coated ML hybrid is about three times higher than the transmission of a hybrid with a fl at metal fi lm having the same nominal thickness but placed beneath the ML. Still the transmission peak of the coated sample is about two times weaker compared to the transmission of the bare ML PhC.…”

“…It was proposed that once the dielectric permittivity in one of the structural components of a PhC possesses a pole at a resonance frequency in the PBG range, the polaritons become normal excitations of this structure.

We review the recently emerged class of hybrid metal-dielectric colloidal photonic crystals. The hybrid approach is understood as the combination of a dielectric photonic crystal with a continuous metal film. It allows to achieve a strong modification of the optical properties of photonic crystals by involving the light scattering at electronic excitations in the metal component into moulding of the light flow in series to the diffraction resonances occurring in the body of the photonic crystal. We consider different realizations of hybrid plasmonic-photonic crystals based on two- and three-dimensional colloidal photonic crystals in association with flat and corrugated metal films. In agreement with model calculations, different resonance phenomena determine the optical response of hybrid crystals leading to a broadly tuneable functionality of these crystals.

The exciton polariton dispersion law is analyzed in a one-dimensional multiple-quantum-well based photonic crystal. An effective approach allowing consideration structures with an arbitrary periodic spatial modulation of the dielectric function and the multilevel structure of the exciton spectrum is developed. It is shown that the condition for the Bragg resonance has to be modified to take into account the symmetry of the exciton states and the non-trivial dispersion law for the electromagnetic waves in photonic crystals. For the particular case of a one-level excitonic susceptibility it is shown that the Bragg resonance occurs when the exciton frequency falls at the high-frequency boundary of the photonic band-gap. The polariton's dispersion law is considered. The angular dependence of the spectrum is analyzed. The effect of multiple exciton levels on the polariton spectrum is discussed.

“…In the technology of producing such a layered semiconductor structure, the molecularbeam epitaxy method is used. Multilayered structures in which modulation of χ and hence of the refractive index is performed on the scale comparable with the electromagnetic radiation wavelength are called photon crystals [6]. Nowadays, they are objects of research of the perspective direction not only in optics, but also in solid state physics.…”

It is demonstrated that the resonant mechanism on inhomogeneities formed for a fixed distribution of dielectric permittivity can underlie the directed self-organization of the electron flow in semiconductors. The behavior of the resonant flow velocity amplitudes depending on the inhomogeneity factors is considered in the ballistic regime.Prigogin and Nicolis [1] considered the self-organizing processes that laid a foundation for the development of thermodynamics of nonequilibrium processes. Among such processes is the formation of spatially-periodic structures (SPS) in the process of electron motion through nonequilibrium plasma. This is due to the fact that the working electric field strength Е, as a rule, is large compared to kТ/еl, where k is the Boltzmann constant, Т is the temperature, е is the electron charge, and l is the characteristic size of the semiconductor structure. In the ballistic (collisionless) regime (BR), this length l is smaller than the momentum relaxation length (l i ). In the quasiballistic regime (QR), when individual scattering events are observed, the above-indicated lengths coincide. At present, GaAs-based structures with total thickness of 1-2 μm can be prepared by the molecular beam epitaxy method in which the BR is observed at temperature Т = 77 K [2]. The BR can also be realized in Ge with thickness of 20 μm at the temperature of liquid helium [3]. At these thicknesses, the main properties of the medium (including its dielectric permittivity) retain their physical meaning, which provides the possibility of application of the classical electrodynamic approach. Bannov et al.[4], who considered the influence of collisions with optical phonons on the dynamics of electron motion, should also be mentioned. When the energy transferred to the electron is higher than the energy of the optical phonon, the electron virtually instantly emits an optical phonon and is scattered on phonons, thereby leading to the transition from the BR to the QR and further to the drift regime. Therefore, low-energy regimes are conventionally used to fulfill the BR and QR conditions.In [5], the influence of a neutralizing positive charge on the SPS formation in an electron flow moving in vacuum was investigated, and the electron response on the inhomogeneous distribution of the neutralizing positive charge was determined. Whereas in vacuum the velocity of directed motion v can be easily made greater than the thermal velocity v t , in semiconductors this condition is realized in the BR, that is, at low temperatures and in highquality structures. The physical reason for the SPS formation during electron beam propagation in vacuum is the Coulomb interaction of electrons with the neutralizing positive charge. In semiconductor structures with variable dielectric permittivity, in addition to the Coulomb mechanism which is much weaker, the SPS formation and resonant properties are caused by the mechanism of forming a built-in gradient of the dielectric permittivity χ and grouping the electron flow due to this effect. In...
