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.
Un système de communication optique à distance comprend une station de base et une station éloignée. La station éloignée comprend un rétroréflecteur, un modulateur à puits quantiques multiples (PQM) et un circuit de commande qui commande le PQM. Un émetteur de station de base envoie un faisceau de lumière d'interrogation au PQM qui module le faisceau de lumière en fonction des informations présentes dans le signal électrique envoyé par le circuit de commande. Le rétroréflecteur renvoie par réflexion le faisceau de lumière modulé à la station de base où un receveur le détecte.
