  • Patent number: 6628854
    Abstract: A connector-type optical transceiver includes optical devices, a silicon-on-insulator (SOI) optical waveguide and a silicon bench whose upper surface is provided with a U-shaped recesses for receiving the optical devices and the SOI optical waveguide, while being aligned to form optical paths. The SOI optical waveguide includes a silicon substrate, a single crystalline silicon layer whose upper surface is provided with waveguide portions, and a silica thin layer interposed between the silicon substrate and the single crystalline silicon layer to prevent light passing through the waveguide portions from being diffused. The silicon bench has v-shaped grooves extending longitudinally along the silicon bench and receives guide pins adapted to guide an external connecting terminal to be connected to the silicon bench.

  • Patent number: 6453096
    Abstract: A jig for the batch production of optical communication apparatuses includes a jig body whose upper surface is provided with a plurality of U-shaped recesses arranged in a matrix array to receive silicon bases each carrying optical devices and a plurality of vacuum holes vertically formed through the jig body, to communication with the respective bottom surfaces of the U-shaped recesses. The silicon bases received by the U-shaped recesses are held onto the bottom surfaces thereof when a vacuum is applied thereto through the vacuum holes. A method using the jig enables batch production by simultaneously processing many silicon bases.
