Optical wave guides and coupling member monolithically integrated on a semiconductor substrate |
摘要 |
A coupling member between an input light wave guide transporting a main light beam and secondary light wave guides each transporting a part of the intensity of the main light beam. The coupling member is monolithically integrated with the wave guides on a semiconductor substrate. The coupling member comprises a plate having parallel surfaces perpendicular to the plane of the substrate. The plate has a refractive index different from that of the main light wave guide. The parallel surfaces of the plate form interfaces separating the propagation medium of the wave guides (I, R, T) from the propagation medium constituted by the plate.
