Multiple Beam Optical Processing
Abstract
The objective of this effort was to develop optical processing technology required to implement high performance signal processing systems. The work concentrated on the evaluation and characterization of GaAs nonlinear etalons and methods of using these etalons in optical processing functions. Experiments included the implementation of a one bit adder using symbolic substitution, a pattern recognizer that can distinguish between simple three spot patterns, an associative memory which can discriminate against two different input objects, and an all optical compare and exchange module which can compare the magnitude of two digital input signals and make an appropriate exchange decision. These experiments, although rudimentary, may be extendable to larger scales upon further development of the optical processing technology. Keywords: Multiple quantum wells; ZnS and ZnSe Interference filters; Associative memory; Gallium arsenide; Photorefractive crystals; Symbolic substitution; Pattern recognition; Optical bistability; Fabry perot etalons; Optical nonlinear directional coupler; Optical logic; Holographic optical elements.
