Applications of photorefractive devices for radio frequency signal processing problems are reviewed. The problems of signal correlation, filtering and adaptive filtering are addressed using the time integrating property of grating formation in photorefractive crystals. The dynamic range of photorefractive crystals is sufficiently large for critical applications such as adaptive signal processing. New system architectures that use photorefractive two-beam coupling are demonstrated for the problems of tunable notch filtering and adaptive notch filtering.<>
