Problems solved by technology

However, there is a problem that the shell and the ferrule occupy a large space on the substrate
[0005] 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
[0006] 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)

Abstract

To provide an optical connection component and an optical connection structure having a small number of parts, in which 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. The optical connecting component, which connects an optical transmission medium and an optical functional part or another optical transmission medium, has a connecting member having a protrusion and a connecting member having a recess, the connecting member having the convex part has a holding part for aligning and holding the optical transmission medium, the connecting member having the recess has an aligning part of which the optical functional part or other optical transmission medium is aligned, and the connecting member having the protrusion and the connecting member having the recess can be freely connected and disconnected by engaging the protrusion and the recess. The optical connecting component further has the holding part which holds the optical transmission medium, the aligning part of which the optical functional part or other optical transmission medium is aligned, a pressurizing means and a pressurizing wall. The pressurizing means pressurizes the optical transmission medium against the pressurizing wall to align the optical transmission medium at the aligning part.

Description

[0001] This application is a divisional application of the earlier application (application date: July 26, 2007, application number: 200710136990.1, invention name: optical connection component and optical connection structure). technical field [0002] The present invention relates to an optical connection component and an optical connection structure. Background technique [0003] 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 co...
