Optical path change member and holding member body
First Claim
Patent Images
1. An optical path change member comprising:
- a holding member body formed of a transparent material, the holding member body comprising;
at least two rows of optical-fiber insertion holes which hold optical fibers inserted therein, such that the optical axes of the optical fibers are inclined with respect to optical axes of light input and output ends on a circuit board, the optical-fiber insertion holes respectively each having a bottom, wherein front ends of respective optical fibers reach the bottom of respective optical-fiber insertion holes, anda reflective inner surface which totally internally reflects light incident from the optical-fiber insertion holes to a surface of the holding member body facing the light input and output ends,wherein the bottoms of the optical-fiber insertion holes are displaced from each other in an insertion direction of the optical fibers in accordance with an incline of the reflective inner surface as approaching the circuit board.

Abstract
Provided is an optical path change member including a holding member body formed of a transparent material. The holding member body includes: at least two rows of optical-fiber insertion holes which hold optical fibers inserted therein, such that the optical axes of the optical fibers are inclined with respect to an optical axis of the optical device, and a reflective inner surface which totally internally reflects light incident from the optical-fiber insertion holes to a surface of the holding member body configured to face an optical device on a board.
