Retroreflecteur de modulation base sur la technologie des puits quantiques multiples

Modulating retroreflector using multiple quantum well technology


A system for remote optical communications includes a base station and a remote station. The remote station includes a retroreflector, a multiple quantum well modulator (MQW), and drive circuitry that drives the MQW. A base station transmitter sends an interrogating light beam to the MQW, which modulates the light beam based on the information in the electrical signal from the drive circuitry. The retroreflector reflects the modulated light beam to the base station for detection by a receiver.
