OPTICAL RECEIVERS FOR LASER COMMUNICATION SYSTEMS NEEDS TO HAVE HIGH DETECTION SENSITIVITY SO THAT ALLOWABLE DISTANCE BETWEEN TRANSMITTING AND RECEIVING STATIONS CAN BE MAXIMIZED.

OPTICAL RECEIVERS FOR LASER COMMUNICATION SYSTEMS NEEDS TO HAVE HIGH DETECTION SENSITIVITY SO THAT ALLOWABLE DISTANCE BETWEEN TRANSMITTING AND RECEIVING STATIONS CAN BE MAXIMIZED. IN THIS STUDY, A HIGHLY SENSITIVE OPTICAL RECEIVER WILL BE DEVELOPED WHICH INCLUDES THE FOLLOWING FEATURES: STATE-OF-THE-ART SIAPD'S WITH EXTREMELY LOW IONIZATION CONSTANT RATIO FOR ION NOISE OPERATION, LOW NOISEGAAS MESFETS AS AMPLIFYING DEVICES, AND THIN FILM CIRCUIT CONSTRUCTION TECHNIQUES. A SENSITIVITY ANALYSIS WILL BE CARRIED OUT, WHICH WILL BE SUPPORTED BY EXPERIMENTAL RESULTSFROM PRELIMINARY CIRCUIT FABRICATION AND EVALUATION.
