OPTICAL FIBER FIXING STRUCTURE, OPTICAL DEVICE PROVIDED WITH THE SAME, AND MANUFACTURING METHOD OF THE OPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical fiber fixing structure capable of positioning an optical fiber with high accuracy even when foreign matters, such as dust and contaminant, are present in manufacturing environment, to provide an optical device provided with the same, and to provide a manufacturing method of the optical device.

SOLUTION: In the optical fiber fixing structure S for inserting an optical fiber F into a fiber insertion part 2 formed in the shape of groove on the surface 1a of a substrate 1 and fix it, a foreign matter removal part 3 storing foreign matters is arranged so as to be open toward the fiber insertion part 2 and to occupy the most part of the part 2 in the groove direction by the opening.
