Optical coupling module and photoelectric conversion device including same

摘要

An optical coupling module includes a top surface, a bottom surface parallel and opposite to the top surface, a front side surface, and a rear side surface parallel and opposite to the front side surface. The bottom surface defines a bottom groove including a first optical surface. Optical coupling lenses are arranged on the first optical surface. The bottom groove further includes a mounting surface parallel to the first optical surface and perpendicularly connected with the front side surface. Grooves in the mounting surface receive and locate optical fibers, which intersect with a straight line along the optical axes of the optical coupling lenses, the straight line runs between the optical coupling lenses and the photoelectric conversion members.
