Paper Abstract

The polaritons are generated at passage of an electromagnetic beam in dielectric Fabry-Perot resonator. The states of polaritons can be treated as ground and excited ones of the quasi-condensate in one- or two-dimensional models (in a cross plane of the resonator). The spectrum of the weak excitations of the quasi-condensate looks like Bogolubov spectrum. The quantum vortices with different topological charges are formed in the polariton quasi-condensate into the dielectric medium. The excitations of polariton quasi-condensate formed the spatial waves with zeros of amplitude on the transverse axes on the mirrors of dielectric Fabry-Perot resonator. There are the inhomogeneities of the permeability in the shape of a superlattice with variable thickness in the dielectric medium appeared by the powerful electromagnetic pump wave. The shape of the superlattice can be controlled by the external electrostatic field. Impinging on the surface of film the weakly signal wave scatters at the superlattice. The bands of "allowed" and "forbidden" frequencies of the signal wave spectrum take place. Such dielectric film represents one-dimensional controllable photonic crystal. The pump wave shapes the superlattice in the rectangular dielectric resonator, i.e. two-dimensional controllable photonic crystal is formed.
