Embodiment Construction

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0043] (Structure of Optical Module)

[0044] figure 2 It is a sectional view of the optical module 100 according to one embodiment of the present invention. figure 2 In FIG. 2 , the hatching of the cross section of the optical receptacle 120 is omitted in order to show the optical path in the optical receptacle 120 .

[0045] Such as figure 2 As shown, the optical module 100 has a substrate-mounted photoelectric conversion device 110 including a light emitting element 114 , and an optical receptacle 120 . The optical module 100 is used by connecting the optical transmission body 116 to the optical receptacle 120 . The type of the optical transmission body 116 is not particularly limited, and includes optical fibers, optical waveguides, and the like. In this embodiment, the optical transmission body 116 is an optical fiber. In addition, the optical fi...

Abstract

This light receptacle comprises: a plurality of first optical surfaces on which light beams emitted from a plurality of light emitting elements are respectively caused to be incident; a plurality of second optical surfaces which emit the light beams incident on the plurality of first optical surfaces respectively toward the end faces of a plurality of light transmission bodies; a third optical surface which reflects the light beams incident on the first optical surfaces toward the second optical surfaces; and a plurality of recesses which are formed in the surface on which the plurality of second optical surfaces are arranged. The distance between the centers of two adjacent first optical surfaces before mold release and the distance between the centers of two adjacent second optical surfaces before mold release during injection molding are shorter than the distance between the optical axes of light beams emitted from two adjacent light emitting elements that are arranged so as to face each other.

Description

technical field [0001] The invention relates to an optical socket and an optical module with the optical socket. Background technique [0002] Conventionally, in optical communication using an optical transmission body such as an optical fiber or an optical waveguide, an optical module including a light emitting element such as a surface emitting laser (for example, VCSEL: Vertical Cavity Surface Emitting Laser) has been used. The optical module has an optical receptacle for transmission that makes light including communication information emitted from a light emitting element incident on an optical transmission body, or an optical receptacle for reception that makes light from an optical transmission body incident on a light receiving element (for example, refer to Patent Document 1 ). [0003] figure 1 It is a perspective view of a receiving optical receptacle 10 described in Patent Document 1. FIG. Such as figure 1 As shown, the optical receptacle 10 has: a plurality ...
