Abstract

UNDER AN INITIAL RESEARCH PHASE, A 2-D ACOUSTO-OPTIC (A-O) EDITECTOR WAS CONSTRUCTED AND INCORPORATED IN A MATRIX MULTIPLICATION SYSTEM. NOT ONLY WAS A 2-D A-O DEVICE BUILT AND AN OPTICAL COMPUTING SYSTEM DESIGNED, BUT A 3X3 OPTICAL MATRIX MULTIPLIER ALSO WAS CONSTRUCTED TO DEMONSTRATE COMPUTING FEASIBILITY. IN THE CURRENT RESEARCH EFFORT BASED UPON PREVIOUS RESULTS, A 2-D A-O 32 CHANNEL DEFLECTOR IS BEING DESIGNED, CONSTRUCTED, TESTED, AND IMPROVED FOR USE IN A PROGRAMMABLE LOGIC ARRAY (PLA) OPTICAL COMPUTING SYSTEM. AN APPROPRIATE 32-FREQUENCY RADIO FREQUENCY SOURCE AND PLA OPTICAL TESTING SYSTEM ARE ALSO BEING DESIGNED AND CONSTRUCTED. AREAS BEING CONCENTRATED ON FOR IMPROVEMENT OF 2-D MULTICHANNEL DEVICE PERFORMANCE INCLUDE DIFFRACTION EFFICIENCY, TIME-BANDWIDTH PRODUCT, DYNAMIC RANGE, AND 2-D MULTICHANNEL TRANSDUCER DEPOSITION FOR USE IN A PLA OPTICAL COMPUTING SCHEME. APPLICATIONS FOR A 2-D A-O DEVICE ARE FOUND IN CONVENTIONAL OPTICAL FAN-IN, FAN-OUT AND FIBER OPTICAL COMPUTING SYSTEMS. OPTICAL PLA COMPUTING SYSTEMS ARE EXPECTED TO EVENTUALLY REPLACE CONVENTIONAL DIGITAL ELECTRONIC COMPUTER SYSTEMS.
