Coupling device between the wave guides monolithically integrated with those - latter on a semiconductor substrate

摘要

Coupling device between a waveguide of light transporting a main light beam and the secondary light waveguides, each carrying a portion of the intensity of the main light beam, this device being monolithic integrated with the guides on a substrate semiconductor - conductor, characterizes in that it is the form of a blade has parallel faces, perpendicular to the substrate and of refractive index different from that of the main waveguide, the parallel faces of the blade forming the diopters of separation between the propagation medium is constituted by the waveguides and the propagation medium is constituted by the blade. / p & & p & application: modulators integrated on substrates made of semi-rigid - conductors.
