Internal-reflection optical path changing member
First Claim
1. An optical path changing member to be assembled at ends of optical fibers and placed to face a substrate including an optical terminal having optical axes inclined with respect to optical axes of the ends, the optical path changing member comprising:
- a member body being made of a transparent material,the member body comprisingoptical fiber insertion holes into which the optical fibers are inserted;
a reflection-surface-formation recess including a reflection surface in an inner surface thereof, the reflection surface optically connecting the optical fibers to the optical terminal, the reflection surface being inclined with respect to the optical axes of the optical fibers and the optical terminal for light entering into the member body from one of the optical terminal and any of end faces of the optical fibers to be internally reflected toward the other in the member body; and
an end placement space to which the optical fiber insertion holes are open, having an inside wall facing openings of the optical fiber insertion holes and contacting with the ends of the optical fibers, and the end placement space being filled with an adhesive to fix the optical fibers therein; and
a cover covering the reflection-surface-formation recess.

Abstract
An optical path changing member is assembled at ends of optical fibers and placed to face a substrate including an optical input/output terminal having optical axes inclined with respect to optical axes of the ends. The optical path changing member is made of a transparent material and includes a member body having a reflection surface for optically connecting the ends to the optical input/output terminal. The member body has optical fiber insertion holes and an end placement portion to which the insertion holes are open and in which the end faces of the optical fibers are placed. The reflection surface is formed so that light entering from the end faces of the optical fibers into the member body will be internally reflected toward the optical input/output terminal in the member body. The end placement portion is filled with an adhesive by which the ends are fixed to the member body.
