Abstract

THIS PHASE II PROPOSAL CONCERNS RESEARCH AND DEVELOPMENT OF NEW OPTICAL MATERIALS OF CERTAIN II-VI COMPOUNDS FOR INFORMATION HANDLING. RECENT QUANTEX MATERIALS DEVELOPMENT HAVE SHOWN THAT SOME OF ITS NEW ELECTRON-TRAPPING (ET) MATERIALS CAN BE MADE IN THE FORM OF THIN FILMS WITH HIGH RESOLUTION. THEY ALSO SHOW LINEARITY OVER ORDERS OF MAGNITUDE IN CHARGING AND DISCHARGING THE TRAPS AS A FUNCTION OF LIGHT INTENSITIES. BESIDES STORING INFORMATION, THE NATURAL LINEARITY LEADS TO HIGH SPEED, HIGH RESOLUTION OPTICAL PROCESSORS AND OFFERS PARALLEL MULTIPLICATION AS WELL. AFTER SOME MATERIALS DEVELOPMENT, PARALLEL OPTICAL PROCESSORS BASED ON THE ET TECHNOLOGY WILL BE STUDIED. IT IS EXPECTED THAT BY THE END OF PHASE II OPTICAL PROCESSING WITH MEMORY WILL BE DEMONSTRATED TO THE POINT OF PRACTICAL USEFULNESS.
