Abstract : The primary goal of this effort was to investigate a new method of demultiplexing time varying optical images using a photorefractive optical mixer. The effort was based upon previous in-house work at Rome Laboratory with Jehad Khoury and Charles Woods. They demonstrated that the technique is valid for low frequencies (<100 Hz). The object of this research was to extend this concept to the range of GHz carrier frequencies. A second effort was to demonstrate that the concept could also be implemented with semiconductor lasers. (MM)
