Title:

OPTICAL COUPLING STRUCTURE AND OPTICAL TRANSRECEIVER MODULE

Document Type and Number:

WIPO Patent Application WO/2011/083812

Kind Code:

A1

Abstract:

Disclosed is an optical coupling structure comprising: an optical semiconductor element that has a light-receiving/emitting part on the upper surface thereof and is mounted on a substrate at the bottom surface thereof; an optical transmission path that has an optical axis that intersects the optical axis of the optical semiconductor element at a specified angle and is arranged apart from the optical-semiconductor-element-mounted surface of the substrate; and an optical coupling part that can convert an optical path between the optical semiconductor element and the optical transmission path and can optically couple the optical semiconductor element with the optical transmission path. The optical coupling part comprises a resin that is transparent to transmitted light, wherein the resin is adhered to both at least a part of a light-receiving/emitting part of the optical semiconductor element and at least a part of the edge part of the optical transmission path, and the optical semiconductor element and the optical transmission path are adhered to each other through the resin that constitutes the optical coupling part.
