FIBER ARRAY SUBSTRATE, FIXING STRUCTURE OF OPTICAL FIBER ARRAY USING THE SUBSTRATE, SUBSTRATE FOR POSITIONING OPTICAL FIBER, AND FIXING STRUCTURE OF OPTICAL FIBER USING THE POSITIONING SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a fiber array substrate in which the positioning of an optical fiber in a substrate thickness direction can be done only by adjusting the aperture width of a groove without requiring the adjustment of the depth of the groove for positioning the optical fiber in the substrate thickness direction. SOLUTION: A plurality of grooves 2 for positioning and aligning a plurality of optical fibers to be formed on a substrate 1 are constituted so as to support each optical fiber 10 by corner parts 3a, 3b formed on both the ends of the aperture part of each groove.
