24 May 2000Optical demodulator with photorefractive cross-polarized duplex two-wave mixing
We propose an optical demodulator with photorefractive cross-polarized duplex two-wave mixing, in which the phase- modulated signal beam is converted into the intensity- modulated output signal beams. We calculate the intensity variations of the output signal beams when phase-modulated signal beam input to photorefractive cross-polarized duplex two-wave mixing.
