Abstract:
1. An optical module comprising: an elongated optical waveguide having multiple cores buried in a clad; a rectangular-shaped silicon optical waveguide substrate, on which said optical waveguide is mounted, and along each side edge of an upper surface of which a high precision step is formed extending in a longitudinal direction of the waveguide substrate; and an optical fiber connecting end member having a hole therethrough for accommodating and fixing an end surface of the optical waveguide substrate, the hole having a top surface, a bottom surface, a first side surface, and a second side surface, wherein: a step is formed on the top surface of the hole, along each side surface of the hole, so as to fit the high precision steps on the waveguide substrate when the waveguide substrate is inserted in the hole, and said end member has a cavity that opens from the bottom surface of the hole to the bottom of said end member, permitting said substrate to be pressed toward the top surface of the hole so as to align the high precision steps on said substrate with the steps of the hole.
