Abstract

Phenomenological theory for non-equilibrium steady states of holographic gratings under stable irradiation is presented. These states can be described in a much simpler manner than the full microscopic picture of the grating formation process: namely, they can be characterized with a single mode of the electromagnetic field (the writing mode), and the respective modulation of the electric permittivity (the photorefractive response). The two latter quantities are interdependent, and should be obtained in a self-consistent manner in the theory. The photonic bandgap that results from the periodic grating, manifests itself as an effect of phase-sensitive birefringence.
