Optical integrated waveguide device, optical transceiver and other optical apparatuses using the optical device

摘要

A receiving light guide is formed by filling, with a core material, a groove that is formed on the top surface of a reception-side substrate. A sending light guide is formed by filling, with a core material, a groove that is formed on the bottom surface of a sending-side substrate. The reception-side substrate and the sending-side substrate are bonded to each other with a cladding layer interposed in between so that the receiving light guide and the sending light guide are isolated from each other optically. <IMAGE> <IMAGE>
