Paper Abstract

By using light as a carrier, the information of voice and data is sent to a receiver through atmosphere, so this system with computer via some interfaces can be applied to link computers into network. This system has shown many advantages on volume weight flexibility, convenience, security and anti- interference. In this paper, firstly, the principle of a laser communication system is introduced, then the performance of LOC, GaAs, AlGaAs semiconductor lasers are presented; moreover, the basis of choosing photo-detector, the characteristic and usage of silicon avalanche photo-detectors, and the threshold detection and false-alarm ratio of the system are presented in detail.
