Abstract

Photorefractive InP:Fe with an applied dc field was used to construct a wide-field-of view heterodyne receiver in a double phase-conjugate mirror configuration. Large double phase-conjugate mirror diffraction efficiencies (>20%) and stable (as a function of signal-beam angle) intermediate-frequency powers were measured over an approximately 8° field of view with a minimum rise time of approximately 65 ms. The influence of electric-field strength and sample temperature on rise time was measured.
