Title:
OPTICAL RECEPTACLE AND OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2020/153427
Kind Code:
A1
Abstract:
Provided is an optical receptacle that can reduce return light to a vertical resonator surface emitting laser while maintaining the coupling efficiency of light to an optical transmission body. The optical receptable, which is disposed between one or more vertical resonator surface emitting lasers arranged on a substrate and one or more optical transmission bodies to optically couple the vertical resonator surface emitting lasers and end surfaces of the optical transmission bodies, has: a first optical surface on which light emitted from the vertical resonator surface emitting lasers is incident; and a second optical surface for emitting light, which enters the first optical surface and passes through the inside thereof, toward the end surfaces of the optical transmission bodies. The first optical surface is disposed such that a central axis of the first optical surface is inclined with respect to an optical axis of the vertical resonator surface emitting laser or the central axis and the optical axis are parallel to and do not coincide with each other.
