Paper Abstract

The laser diode is widely used in optical fiber communications and intersatellite optical communication. And there are some differences between the modulator of laser diode in these two communications. This paper has mainly analyzed the modulation in these two communications. And because the high power AlGaAS semiconductor lasers operating around 800 nm have been successfully qualified for deployment in many intersatellite optical communication programs, in this paper we have given the experimental simulation results of some modulation methods by using the model of laser diodes. From the simulation results, we have compared the methods of laser diode modulation. And we can know which method is suitable for optical space communications, which demand both high power and high bandwidth.
