ABSTRACT:
A light-emitting and light receiving diode comprises an active zone which, in the emitting mode, is the seat of a strong current. The emission surface has a central semiconducting region which channels the current lines and an insulating region transparent to light. In the receiving mode, the photons pass through the entire receiving surface which is none other than the emission surface and the active zone has a sufficient thickness and a sufficiently low doping concentration to be in the space charge state.
