Problems solved by technology

However, when subjected to an accelerated test such as a temperature cycle test or placed in an environment such as high temperature and high humidity, the transmission efficiency of the optical waveguide may decrease near the first ferrule, and the coupling efficiency of optical coupling with the optical fiber may decrease.
It is generally known that in optical waveguides, the transmission loss is increased by applying pressure

Abstract

The purpose of the present invention is to provide: an optical wiring component which is capable of connecting an optical waveguide to another optical component with high coupling efficiency, while suppressing decrease in the transmission efficiency; and a highly reliable electronic device which is provided with this optical wiring component. The present invention provides an optical wiring component which comprises a band-like optical waveguide and a ferrule that has a through hole penetrating therethrough from the base end to the front end, and wherein a part of the optical waveguide in the longitudinal direction is inserted into the through hole. This optical wiring component is characterized in that: at least one of the two major surfaces of the optical waveguide is affixed to the inner wall of the through hole; and spaces are respectively provided between the two lateral surfaces of the optical waveguide and the inner wall of the through hole.

Description

technical field [0001] The present invention relates to an optical wiring component and electronic equipment. [0002] this application claims priority based on Japanese Patent Application No. 2012-263479 for which it applied to Japan on November 30, 2012, and uses the content here. Background technique [0003] Optical communication technology that transmits data using an optical carrier has been developed, and in recent years, optical waveguides and optical fibers have become popular as means for guiding the optical carrier from one point to another. Among them, the optical waveguide has a linear core and a cladding provided to cover its periphery. The core is made of a material that is substantially transparent to the light of the optical carrier, and the clad is made of a material with a lower refractive index than the core. [0004] In the optical waveguide, light introduced from one end of the core is conveyed to the other end while being reflected at the boundary wi...
