Title:
OPTICAL RECEPTACLE AND OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2022/145001
Kind Code:
A1
Abstract:
An optical receptacle (140) has a first incidence surface (141) for causing first light emitted from a first light emitting element to be incident thereon, a second incidence surface (142) for causing second light emitted from a second light emitting element to be incident thereon, and an emission surface (144) for causing the first light incident on the first incidence surface and traveling through the optical receptacle and the second light incident on the second incidence surface and traveling through the optical receptacle to be emitted toward an optical transmitter. The curvature of the emission surface in a first cross section (CS1) of the emission surface is smaller than the curvature of the emission surface in a second cross section (CS2) of the emission surface, the first cross section being parallel to a first surface including a first optical axis of the first light and a second optical axis of the second light, and the second cross section being parallel to the first optical axis or the second optical axis crossing the emission surface and being orthogonal to the first surface.
