9 June 1992 Direct phase modulation of laser diodes
Author Affiliations +
TRW was awarded a U.S. patent for direct phase modulation of laser diodes. The scheme can replace an electro-optic modulator with an electrical filter, greatly enhancing the practicality of heterodyne or homodyne P5K optical communication systems for satellite and fiber optic applications. The technique is described, simulation results are presented, filter designs are discussed and some experimental work is referenced.
