Cat’s eye modulating retro-reflector makes fast ATP, very high speed, small, light and low power consumption free space optical communication link possible. This paper analyzes the principle of free space optical communication based on cat’s eye modulating retro-reflector using a multiple quantum well spatial light modulator, and introduces the principle of GaAs/AlGaAs multiple quantum well using as a spatial light modulator. An experiment has been done to test characteristics of a GaAs/AlGaAs multiple quantum well device used as a spatial light modulator. An experimental free space optical communication system based on cat’s eye modulating retro-reflector using GaAs/AlGaAs multiple quantum well was built, and a communication link was tested using it with the maximum rate of 50Mbps. The results show that GaAs/AlGaAs contrast ratio is a key factor to the communication link, which is influenced by drive voltage, incidence angle and modulating speed.
