The present work is devoted to the theoretical study of non-reciprocal optical properties in a periodic multilayer systems composed by hybrid two-layers (isotropic/anisotropic) and for photon energies close to the electronic energy gaps of semiconductors (excitons). The optical properties of these resonant non-magnetic photonic crystal, where linear and quadratic spatial dispersion effects are both present, will be computed in the framework of exciton-polariton by self-consistent Maxwell-Schroedinger equation solutions in the effective mass approximation. The main interesting optical properties, namely: negative refraction, giant transmission, absorption suppression, optical unidirectional propagation will be computed by implementing a simple two-layers "minimum model".
