Optical connecting parts and optical connecting structure

Abstract

Optical connecting parts and an optical connecting structure are provided. A large area is not occupied on the substrate, position aligning is easier, it takes less time to connect, and connecting and releasing can be freely performed. Optical connecting parts which connect an optical transmission medium and optical functional part or another optical transmission medium vertically, has a connecting member having a convex part (100) and a connecting member having a concave part (200), the connecting member having the convex part (100) has a holding part of which the optical transmission medium is aligned and held, the connecting member having the concave part (200) has an aligning part of which the optical functional part or other optical transmission medium is aligned, and the connecting member having the convex part and the connecting member having the concave part can be freely connected and disconnected by engaging the convex part and the concave part.

Description

technical field [0001] The present invention relates to an optical connection component and an optical connection structure. Background technique [0002] Conventionally, in order to connect optical functional components to a substrate, an optical connection structure having an optical transmission medium has been used. In the optical connection structure, there are connections in the so-called parallel direction to the substrate in which an optical fiber as an optical transmission medium is attached to a ferrule to make it interface with an optical functional component along the substrate, and the end of the optical fiber is slanted. A so-called connection perpendicular to the substrate is cut and brought into contact with an optical functional component having a connection point opening in a direction perpendicular to the substrate. [0003] In an optical connection structure for connecting in a direction parallel to the substrate, generally, an optical connector or the l...

AI Technical Summary

Problems solved by technology

However, there is a problem that the shell and the ferrule occupy a large space on the substrate

[0004] In addition, in the optical connection structure that is connected in the direction perpendicular to the substrate, the processing of the optical transmission medium is difficult, and there is no effective alignment method

Therefore, it is difficult to perform a stable connection, and there is a possibility of damage to the optical functional component when, for example, contacting the optical functional component and the optical fiber

[0005] Optical connections can be made using reflective layers such as lenses without contact, but the number of parts is large, and the time required for connection becomes longer due to the alignment of reflective layers, optical functional parts, and optical transmission media, and there are problems with increased costs (for example, Refer to Japanese Unexamined Patent Publication No. 9-026515)
