Latest Patents
One of his latest patents is for a compact optical structure with an integrated source. This invention relates to a compact optical structure that includes a semiconductor emitter junction, such as a laser or a light-emitting diode, coupled to a plane waveguide formed by a layer of photo-polymer deposited on a substrate with a suitable index. The surface layer of photo-polymer enables the registration of photo-induced diffraction structures that perform specific optical functions, including that of a distributed reflector, deflector, or lens. These compact structures are particularly applicable in designing simple, small devices, laser sources with distributed external resonators, interferometric gyrometers, hydrophones, multiplexers, or demultiplexers.
Another significant patent involves a solid-state semiconductor element and the contact thereupon. This device features a laser diode with an upper face of gallium arsenide, which is partly covered with titanium, forming an ohmic contact of low resistivity with the gallium arsenide. Beneath the gallium arsenide, an active layer for emitting light is interposed between two layers, forming a heterojunction. The assembly is covered with gold, which forms an ohmic contact of much higher resistivity with Ga As. Consequently, the lines of current and light emission are localized under the titanium.
