Optical fiber connecting structure and optical fiber connector

摘要

Provided is an optical fiber connecting structure wherein: a first optical fiber and a second optical fiber optically connected to the first optical fiber via a solid index matching material attached to a tip surface of the first optical fiber are held and fixed between a base member and a cover member; a tip of the second optical fiber is disposed so as to come into contact with the solid index matching material or be separated from the solid index matching material; and the solid index match material as a whole and the tip of the second optical fiber are disposed within a liquid index matching agent provided between the base member and the cover member.
