MICROWAVE GENERATION USING LASER HETERODYNE TECHNIQUE WITH INDEPENDENT CONTROLLABILITY IN FREQUENCY AND PHASE

This paper describes the theoretical and experimental Investigation of a scheme for microwave generation using laser heterodyne. The frequen cy of the generated microwave is controlled by changing the frequency difference between two temperature-controlled semiconductor laser diod es. The phase difference between the two microwaves is controlled by c hanging the difference between the two states of polarization of two l aser beams. An attractive feature of this scheme is its easy and indep endent controllability in frequency and phase.
