Abstract:
1. An optical waveguide mounting member for mounting to a substrate, the optical waveguide mounting member comprising: an optical waveguide for transmitting optical signals therethrough; and an optical waveguide mounting base material having first and second planes and a through-hole to which the optical waveguide is mounted from the first plane to the second plane, in a direction perpendicularly intersecting an optical element mounted on top of the first plane; wherein the optical waveguide mounting base material is formed of silicon wherein the optical waveguide has first and second ends that protrude from the first and second planes and are polished to be flush with respect to the first and second planes prior to mounting the optical waveguide mounting member to the substrate; wherein the distance between the polished first and second ends is substantially equal to the thickness of the substrate when mounting the optical waveguide mounting member to the substrate.
