Microwave signal generation with injection-locked laser diodes
Abstract
Goldberg et al. (1982) have reported injection locking of a slave laser (SL) to FM sidebands of a modulated master laser (ML). A narrow band beat signal near 2 GHz was generated by coherent mixing of the light from the SL locked to the first sideband of the ML with the ML carrier using a silicon avalanche photodiode for detecting the beat signal. The present investigation is concerned with the generation of a microwave signal using two slave lasers, injection-locked to different sidebands of a single, modulated master laser. The outputs of the SLs were coherently heterodyned to generate a spectrally narrow beat signal at 10.5 GHz. Possible applications for the described technique are related to the injection locking and control of microwave oscillators and frequency multiplexed optical communications.
