Abstract

An optical homodyne PSK detection scheme based on the photorefractive effect in BaTiO₃ has been investigated. The system uses polarization locking to implement a polarization insensitive receiver using all optical processing and only one detector. A theoretical analysis of the detection process is presented and verified experimentally. The system is shown to have a sensitivity of -52 dBm with S/N=2. The rate at which the system responds to changes in the incoming signal state of polarization is also investigated
