Embodiment approach 1

[0048] (Structure of Optical Module)

[0049] figure 2 It is a cross-sectional view of the optical module 100 according to Embodiment 1 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 .

[0050] 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 fiber may be either a single-mode type or a multi-mode type.

[0051] The photoelectric conversion device 110 has a s...

Embodiment approach 2

[0071] The shape of the optical receptacle 220 of the optical module according to the second embodiment is different from that of the optical module 100 according to the first embodiment. Therefore, the same reference numerals are assigned to the same constituent elements as those of the optical module 100 according to Embodiment 1, and description thereof will be omitted, and the description will focus on different constituent elements of the optical module. Optical receptacle 220 of Embodiment 2 differs from optical receptacle 120 of Embodiment 1 in that it has a plurality of recesses 221 instead of first recesses 124 and second recesses 125 .

[0072] (Structure of optical socket)

[0073] FIG. 7 is a diagram showing the configuration of an optical receptacle 220 according to Embodiment 2 of the present invention. Figure 7A It is a plan view of the optical receptacle 220 of Embodiment 2, Figure 7B is a bottom view, Figure 7C is the main view, Figure 7D is the rear v...

Abstract

An optical receptacle has first optical surfaces via which light outputted by respective light-emitting elements is inputted, a second optical surface whereby light inputted via said first optical surfaces is outputted towards an end face of a light-transporting body, a third optical surface whereby light inputted via the first optical surfaces is reflected towards the second optical surface, a plurality of first concavities formed in the surface where the second optical surface is located, and a plurality of second concavities formed in the surface where the first optical surfaces are located or a surface opposite the surface where the first concavities are located. The first concavities and the second concavities are laid out opposite each other so that the central axes thereof coincide.

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 ...
