Research abstract
MICROWAVE FIBER OPTIC LINKS PROVIDE PERFORMANCE AND COST ADVANTAGES FOR ANTENNA REMOTING, MICROWAVE COMMUNICATIONS, AND SATELLITE EARTH TERMINALS. E-TEK WILL ANALYZE AND PERFORM TRADEOFFS ON THE CRITICAL SYSTEM RELATED ISSUES INCLUDING LASER NOISES, SPECTRAL LINE-WIDTH, IMPEDANCE MATCHINGS, OPERATION BANDWIDTH, MICROWAVE DEVICE PACKAGES, PRECISION ALIGNMENT, ETC.. DIRECT DETECTION AND COHERENT DETECTION ARE BOTH INCLUDED IN PHASE I R&D. COHERENT DETECTION CAN PROVIDE A 10 TO 20 DB SYSTEM SIGNAL-TO-NOISE RATIO (SNR) ADVANTAGE OVER DIRECT DETECTION. SYSTEM PARAMETERS (SYSTEM SNR, DYNAMIC RANGE, NONLINEAR DISTORTION,GROUP DELAY DISTORTION, PHASE LINEARITY, AM/PM CONVERSION, AND FREQUENCY RESPONSE) WILL ALSO BE INVESTIGATED. FURTHERMORE, IN PHASE I, A 12 GHZ, 1 KM FIBER OPTIC SYSTEM AT 1.3 UM WAVELENGTH WILL BE DESIGNED AND FABRICATED TO DEMONSTRATE THE FEASIBILITY AND VIABILITY.
