Optical devices based on polarized light filters

Abstract

The paper presents several concepts of devices based on anisotropic crystals, which permit to separate polarized light signals. The devices are elaborated using semiconductor waveguides and ZnAs2 layers, which can filter the polarization plane of optical signals and can operate as switches or splitters of polarized light. These prototypes assure the interleaving/deinterleaving operations used in modern optic communication systems.
