Abstract
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.
