ABSTRACT:
A phototransistor which is capable of operating alternately in the emission mode and in the reception mode can be coupled under favorable conditions to an optical fiber in a telecommunications system. An active layer constitutes the base of the transistor and forms a heterojunction with two layers of opposite conductivity type which constitute the emitter and collector of the transistor. The base contact is formed by a heavily doped region of the same conductivity type as the active layer and defines the useful zone of photon coupling between the optoelectronic component and the entrance face or exit face of the optical fiber.
