A bidirectional light waveguide communications system comprising a light waveguide and a light source, preferably formed by a laser, at one end of a light waveguide, and having a reflection transmitter at the other end. The reflection transmitter is formed by an electrically controllable integrated optical Fabry-Perot resonator whose strip electrode is terminated by two partially reflecting mirror layers and whose control electrodes are charged with a transmission signal. The opto-electrical transducer of the subscriber is positioned adjacent one of the partially reflecting mirrored layers, while the other partially reflecting mirrored layer is connected to the light waveguide.

Reflection transmitter and receiver means for a bidirectional light

A bidirectional light waveguide communication system that has a light source preferably formed by a laser at one end of the light waveguide and a reflex transmitter at the other end of the waveguide with the reflex transmitter formed by a halved controllable optical directional coupler which has two strip waveguides that are terminated by a partially reflecting mirror and which has control electrodes which receive a transmission signal. An opto-electrical transducer receives the received light signal from both strip waveguides after the partially reflecting mirror.
