Optical demodulator with photorefractive cross polarized duplex two-wave mxing

摘要

We propose an optical demsodulator with photorefractive cross-plarized duplex two-wave mixing, in which the phase-modulated signal beam is converted into the intensity-modulated ouput signal beams. We calculate the intensity variation of the oputput signal beams when phase-modulated signal beam input to photorefractive cross-polarized duplex two-wave mixing.
