Optical waveguide with integrated transistor structure and applications to the production of laser modulators and optical couplers

摘要

Optical waveguide comprising, on a substrate S,: - a first layer (2) in n-doped semiconductor, serving as a collector for the control transistor and as guide layer; - a second layer (4) in p-type doped semiconductor and serving as base for the transistor; - a rib (5, 6) in n-type semiconductor serving as a lateral guide for an optical wave and as emitter for the transistor. Applications: waveguides Optical modulators Optical changeover switches Optical couplers. <IMAGE>
