Item type:Item, OPTOELECTRONIC SYNCHRONIZATION OF DISTRIBUTED MICROWAVE-OSCILLATORS USING SEMICONDUCTOR-LASER DIODES(1992-09-01) ;WU, HH ;CHANG, CS ;PAN, CL ;交大名義發表光電工程學系We report a laser-diode-based system for optoelectronic synchronization of two distributed microwave oscillators at 10-GHz. The relative phase between the 10-GHz signals can be continuously tuned over a complete cycle by an optical delay line. Phase-locking of the two oscillators with a frequency offset of 10 kHz is also demonstrated. This method can be used to synchronize millimeter-wave oscillators for distributed architectures via fiber-optic links in the future.Item type:Item, A NOVEL OPTOELECTRONIC PHASE-LOCKED LOOP BASED ON A SQUARE-WAVE PHASE-MODULATED STATIC FIBEROPTIC GYROSCOPE(1992-12-15) ;PAN, CL ;CHIEN, PY ;交大名義發表 ;光電工程學系National Chiao Tung UniversityWe propose and demonstrate a novel optoelectronic phase-locked loop (OEPLL). The key element of the OEPLL is an electro-optic harmonic mixer consisting of a square-wave phase-modulated static fiber-optic gyroscope (FOG) with an intensity-modulated laser diode as the light source. As a first demonstration, we have phase-locked a target electronic oscillator modulating the laser diode at the 10th harmonic frequency of the reference oscillator which modulates the phase of the FOG.Item type:Item, OPTOELECTRONIC PHASE-TRACKING AND WAVE-FORM DISPLAY OF MICROWAVE SIGNALS UP TO 8 GHZ USING GAIN-SWITCHED LASER-DIODES(1994-05-15) ;WU, HH ;WANG, CL ;LIN, GR ;CHANG, CSPAN, CLWe present a new, more versatile scheme for maintaining phase coherence between optical probe pulses and microwave signals under test in a laser-diode-based optoelectronic sampling system. This approach takes advantage of the relative ease of changing the repetition rate of the gain-switched laser diode (GSLD). The microwave signal to be sampled is used as the clock signal for phase-locking of a voltage controlled-oscillator (VCO) which drives the GSLD. Phase-tracking and display of waveforms at frequencies up to 8 GHz have been realized. It is also shown that lower phase noise sidebands for the phase-locked VCO can be realized by locking the higher harmonics of the laser pulse to the microwave clock.
