Abstract
A four-wave mixing (FWM) optical correlator created by using a thin photorefractive (PR) bismuth silicon oxide (BSO) crystal plate is demonstrated. The envelope function which limits the shift-invariant range of the volume holographic correlator is derived. The optimum conditions for obtaining a compact shift-invariant FWM correlator are described. Both experimental and simulated results are presented.
