ABSTRACT:
A planar-mounted optical waveguide transmitter-receiver module has a plurality of separated silicon substrates and a PLC substrate hybrid-integrated. In this module, electrical crosstalk between the light emitting element side and photo-receiving element side is reduced, and an adhesion area between substrates is decreased. In this module, a first silicon substrate, on which are mounted a light emitting element and photo-receiving element, is positioned opposing a second silicon substrate, in which is formed a V groove, in which an optical fiber is to be inserted and fixed in place with resin or by other means. On joining surfaces of the first silicon substrate and joining surfaces of the second silicon substrate are positioned and fixed in place joining surfaces on the back face of the optical waveguide (PLC) substrate, in which is formed an optical waveguide. By this means, the light emitting element, the photo-receiving element, and the optical fiber inserted into the V groove are optically aligned with and simultaneously optically coupled with the optical waveguide of the PLC substrate.
