Abstract:
A method of manufacturing an optical fiber array module using soldering, comprising the steps of:forming holes into which optical fibers can be inserted, in one of either a silicon wafer substrate or a ceramic substrate at predetermined intervals;forming a metal layer on walls of the holes and an entire surface of the substrate, to facilitate the walls of the holes and the entire surface of the substrate to be plated with a solder alloy material;plating the walls of the holes and the entire surface of the substrate with the solder alloy material;inserting metal-coated optical fibers into the holes plated with the solder alloy material;positioning the optical fibers at the centers of the holes using the surface tension of the solder alloy material, by heating the resultant structure of the substrate and optical fibers;fixing the optical fibers, inserted into the holes of the substrate, to the substrate by pouring an epoxy curable by heat or ultraviolet light thereon, to fabricate a fiber array module capable of being accurately attached to an optical waveguide device; andpolishing an end of the optical fiber module formed of optical fibers protruding through the holes, to provide optical luminance.
