INTEGRATED OPTICS SCANNER FOR WAFER INTERCONNECT

CONVENTIONAL INTERCONNECT AND SWITCHING TECHNOLOGY HAS BEEN IDENTIFIED AS A LIMITATION IN HIGH THRUPUT PROCESSORS AND COMPUTERS. WAFER SCALE INTEGRATION IS ONE TECHNIQUE TO RESOLVE INTERCONNECT PROBLEMS. METHODS OF INTERFACING TO WAFER SCALE DEVICES WILL RESOLVE INTERCONNECT PROBLEMS. METHODS OF INTERFACING TO WAFER SCALE DEVICES WILL REQUIRE OPTICAL INTERCONNECT TECHNIQUES. IMPLEMENTING COMMUNICATION IN AVIONICS SYSTEMS EMPLOYING FULL WAFER UNION BY MENAS OF A FREE SPACE OPTICAL LASER BEAM COMMUNICATION LINK IS PROPOSED. THE IMPLEMENTATION IS BASED UPON A LASER SCANNING CONCEPT DEVELOPED BY APA OPTICS. THE LASER SCANNING CONCEPT WAS SHOWN FEASIBLE IN A NASA PHASE I SBIR PROGRAM. THE CONCEPT IS UNIQUE IN PERMITTING LASER SCANS OF LARGE ANGULAR DEFLECTION WITHOUT THE USE OF MOVING PARTS. WHEN INTEGRATED INTO FULL WAFER SCALE PACKAGING OF AVIONICS IT CAN PROVIDE THE COMMUNICATION CAPABILITY NEEDED IN HIGH THROUGHOUT SYSTEMS. THE KEY ELEMENT IN THE PROPOSED WORK IS THE DEVELOPMENT AND DEMONSTRATION OF A MEANS OF EFFICIENCY CONTROLLING A TWO-DIMENSIONAL LASER COMMUNICATION BEAM SCAN.
