Paper Abstract

Heterodyne-type optical communication will provide a wide bandwidth and a high signal-to-noise ratio. However, at present the frequency drift of semiconductor lasers is the greatest difficulty, which must be overcome before the heterodyne-type communication is realized. This paper describes an automatic frequency control system for GaAkAs semiconductor lasers. The frequency drift can be reduced to below 10 MHz. Besides, without sacri ficing the frequency stability, a tunable frequency range of 0.5 THz is obtained. These values are good enough for heterodyne-type optical communication systems.
