Connector-type optical transceiver using soi optical waveguide

摘要

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.
