OPTICAL RECEPTACLE AND OPTICAL MODULE

Title:

OPTICAL RECEPTACLE AND OPTICAL MODULE

Document Type and Number:

WIPO Patent Application WO/2022/144999

Kind Code:

A1

Abstract:

An optical receptacle according to the present invention has: a first optical surface through which light emitted from a photoelectric conversion element enters or through which light having emitted from an end surface of an optical transmission body and having passed through the inside of the optical receptacle is emitted toward the photoelectric conversion element; and a second optical surface through which light having entered the first optical surface is emitted toward the end surface of the optical transmission body or through which light emitted from the end surface of the optical transmission body enters. When an intersection point of the optical axis of the first optical surface and the first optical surface is defined as an origin, the optical axis of the first optical surface is defined as a Z axis, the axis passing through the origin and perpendicular to the Z axis is defined as an X axis, and the axis perpendicular to the Z axis and the X axis is defined as a Y axis, the first optical surface is configured such that, when collimate light enters through the first optical surface from the inside of the optical receptacle, a first focal point observed when viewed along the direction of the X axis and a second focal point observed closer to the first optical surface as compared with the first focal point when viewed along the direction of the Y axis are formed.
