Non-Linear Optical Signal Processing
Abstract
In this work we presented a two port nonlinear joint transform correlator with two complimentary results. This correlator is based on a two port photorefractive limiting quadratic processor. In the limiting regime we demonstrated experimentally and by computer simulation, that the correlation operation is like a phase extraction correlator operation, regardless of the sign 0 the coupling coefficient. However, for positive coupling coefficients and intermediate beam ratios, one port performs as a phase-only filter and the other as a classical matched filter.
