HIGH MODULATION RATE OPTICAL TRANSMITTER

ANTENNA REMOTING, PHASED-ARRAY ANTENNA AND SIGNAL PROCESSING FOR COMMUNICATIONS, RADARS AND ELECTRONIC WARFARE REQUIRE FIBER OPTIC COMPONENTS/TRANSMITTER/RECEIVER OPERATING FREQUENCY UP TO 60 GHZ. FIBER OPTIC TRANSMITTERS AND RECEIVER (TX/RX) HAVE BEEN DEMONSTRATED BY E-TEK UP TO 30 GHZ. THE TX/RX OPERATING IN FREQUENCY RANGE OF 30-60 GHZ SHALL HAVE HIGH SENSITIVITY, WIDE DYNAMIC RANGE, GOOD SNR, AND REQUIRING LOW RF DRIVING POWER. DURING PHASE I R&D, E-TEK WILL INVESTIGATE AND ANALYZE VARIOUS EOMS AND LASERS OPERATING IN 40-60 GHZ REGION. SPECIAL PACKAGE TECHNIQUE WILL BE STUDIED IN 40-60 GHZ RANGE TO MINIMIZE PARASITIC EFFECTS. DEVICES CHARACTERIZATION AND NONLINEARITY/NOISE IN REDUCTION ARE ALSO TO BE INVESTIGATED IN 40-60 GHZ BAND. THE OPTICAL DEVICE AND TRANSMITTER DESIGNS WILL DIRECTLY LEAD TO PHASE II HARDWARE FABRICATION, EVALUATION AND DEMONSTRATION.
