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

The optical receptacle of the present invention has: a plurality of first optical surfaces, which make the light emitted from a plurality of light-emitting elements incident; The end faces of the transmission body respectively emit; the third optical surface reflects light incident on the first optical surface toward the second optical surface; and a plurality of recesses are formed on the surface on which the plurality of second optical surfaces are arranged. In injection molding, the distance between the centers of the adjacent two first optical surfaces before demoulding and the distance between the centers of the adjacent two second optical surfaces before demoulding are compared with the distance between the two adjacent adjacent optical surfaces facing each other. The distance between the optical axes of the light emitted from the light emitting element is short.

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 ...
