    摘要: Process for the production of a monolithic integrated optical device incorporating a semiconductor laser and an optical waveguide, as well as to a device obtained by this process.The substrate is given a profile having at least one step. On said substrate is deposited by a single epitaxy operation performed in the vapour phase and in a successive manner a first confinement layer, a guidance layer made from a material transparent for the radiation emitted by the laser, a second confinement layer, an active layer, a third confinement layer and a contact layer. The transparent material has a refractive index higher than the indices of the confinement layers surrounding the same. Thickness values are given to the different layers such that the active layer of the lower stack faces the transparent layer of the upper stack.Application to optical telecommunications.

    摘要: Method for making an integrated guide/detector structure made of a semiconductive material. This method consists of epitaxially growing on a semiconductor (2, 1) a lower confinement semiconductive film (4), a semiconductive guide film (6) and an upper semiconductive confinement film (8) with the same type of conductivity, the guide film being inserted between the confinement films having a prohibited band of energy smaller than that of the confinement films, of etching the upper film so as to form a guide strip with one extremity defining a first step (12) ending by a lateral broadening (28a) inside a plane parallel to the epitaxial films, of etching the released guide film so as to form a second step (16) adjacent to the first step, of epitaxially growing a semiconductive detector film (18) with this type of conductivity whose prohibited band of energy is smaller than that of the confinement films and the guide film, of eliminating that portion of the detective film covering the guide strip, and of forming the detector in the detecting film opposite the steps so as to embody a butt coupling between the guide film and the detector.

    摘要: Process for manufacturing a semiconductor laser having a buried ribbon. After making a double heterostructure (2, 3, 4, 5) on a substrate (1), there is implanted in the contact layer (5) a p-type doping material, which has the effect of rendering it amorphous. The unit, except for a ribbon, is etched which leaves a mesa. A resumption of epitaxy makes it possible to bury the channel. This resumption does not lead to a crystalline growth on the upper surface of the contact layer, although the annealing that takes place during the resumption of epitaxy gives good ohmic contacts at the level of the implanted layer.

    摘要: A double heterostructure stack comprising confinement layers (CC) enclosing active layers (CA) is formed on a substrate (S), e.g. a N+ type gallium arsenide substrate. Selective etching is performed so as to lay bare the confinement layers at different depths, e.g. CC4, CC3, CC2. The confinement layers initially receive contact layers (CP) made of P-type gallium arsenide. Regions R1, R2, and R3 are formed through the contact layers to constitute junctions with the uppermost active layers (respectively CA1, CA2, CA3). Valleys (V10, V21, V32) are formed to isolate the above-defined elementary stacks. After a metal contact layer has been formed, and after the end surfaces have been optically prepared, a multi-wavelength laser device is obtained.

    摘要: In a process for producing integrated structures having at least one cleaved optical guide, the following are successively epitaxied onto a planar surface of a monocrystalline substrate parallel to a plane of the substrate having crystal orientation : an etching barrier layer for the substrate, a lower optical confinement layer, an active layer and an upper optical confinement layer. Then, the epitaxied layers are etched to form an optical guide strip having a portion oriented parallel to a first direction of crystal orientation of the substrate.
