Optical Computing Using Phase Conjugation
One of the most interesting areas of research to emerge since the birth of laser is that of nonlinear optics. Many nonlinear phenomena such as second harmonic generation, parametric conversion, and stimulated Raman scattering have been extensively pursued as means of generating coherent optical radiation throughout the spectrum. One area of nonlinear optics, optical phase conjugation (OPC), has been receiving a great deal of attention over the past few years, not because of the production of new wavelengths, but because it offers attractive solutions to several problem area arising in a variety of applications. Such applications include adaptive optics, active imaging, high brightness lasers, laser energy and power scaling, and optical communications. Several works exist in the literature1−3 dealing with the physics and applications of OPC; this work will focus on its potential application to optical data processing and optical computing.
