Homodyne detection of phase-modulated optical signals through photorefractive crystals

Analytical solutions for the equations that describe the steady-state photorefractive two-wave mixing with rapidly phase-modulated beams are presented. The results show that the volume index of refraction grating automatically aligns so that it coherently couples the signal and local oscillator fields just like a fixed beamsplitter in a conventional homodyne receiver structure.
