QUASI-OPTICAL, SOLID-STATE MULTIPLIER SOURCES TO 3000 GHZ

THIS PROJECT SEEKS TO DEVELOP INNOVATIVE, QUASI-OPTICAL, SOLID-STATE MULTIPLIER SYSTEMS THAT, WHEN PUMPED BY EXISTINGSOLID-STATE SOURCES, WILL GENERATE OUTPUT AT FREQUENCIES UP TO 3000 GHZ. CW OUTPUT POWERS OF 1 WATT ARE ANTICIPATED AT FREQUENCIES <100 GHZ; OUTPUT POWERS OF 1 TO 100MW ARE EXPECTED IN THE FAR-INFRARED (300-3000 GHZ) SPECTRAL REGION. ARRAYS OF NON-LINEAR DIODES WILL BE PRODUCED MONOLITHICALLY, THEREBY ELIMINATING THE POWER LIMITATIONS ASSOCIATED WITH INDIVIDUAL MULTIPLIER SYSTEMS. A NOVEL, QUASI-OPTICAL RING CAVITY WILL BE USED TO COUPLE THE PUMP AND MULTIPLIED EMISSION. THE SYSTEM OPERATION HAS SIMILARITIES TO A LASER AND, THEREFORE, RESULTS IN AUTOMATIC, PHASE-LOCKED OPERATION. THE PRIMARY GOALS OF PHASE I WILL BE TO DETERMINE (THROUGH ANALYSIS AND EXPERIMENT) THE OPTIMUM QUASI-OPTICAL APPROACH FOR THE VARIOUS DESIRED FREQUENCY BANDS, AND TO EVALUATE, THROUGH COMPUTER MODELING, THE MOST DESIRABLE NON-LINEAR DEVICE, THEREBY ESTABLISHING THE DESIRED FABRICATION PARAMETERS. PHASE II WOULD INVOLVE THE DETAILED DESIGN, CONSTRUCTION, AND TEST OF THE MOST APPROPRIATE QUASI-OPTICAL MULTIPLIER SYSTEMS IDENTIFIED IN PHASE I.
