Abstract: PROBLEM TO BE SOLVED: To provide an optical coupling structure for interfacing between an optical device arranged on a substrate with an optical waveguide formed on the substrate. SOLUTION: A method for manufacturing an optical coupling element includes steps for: preparing a wafer 130 formed on an inorganic solid material on a dicing tape 140; cutting the back surface of the wafer 130 to form substantially angled portions using a dicing blade 142 having a point angle; and stripping the dicing tape 140 from the wafer 130 and separating the wafer at the valleys between the substantially angled portions to obtain a three-dimensional polyhedral light-reflecting member 114, which includes a mirror surface corresponding to a surface M of the wafer 130, as an optical coupling element. The obtained optical coupling element 114 is inserted into a trench, which opens in the substrate main surface of an optical transmission substrate 100 while crossing the optical waveguide 106a of the optical transmission substrate 100 substantially perpendicularly, to provide an optical coupling structure with the outside.

Abstract: Disclosed is a method for optimally designing a layout for a plurality of optical waveguides in which the optical waveguides are configured in a planar configuration that creates one or more intersections. Each of a plurality of waveguides bundled at the input end are branched into two, and a plurality of default routes are set for all of the plurality of the waveguides, such that a given branched waveguide forms at least one intersection with other branched waveguides, and such that the branched plurality of waveguides can be bundled at least at two or more separate places on the output end. The intersections that exist in a route are counted, and a default value (branching ratio) for a cross-section (thickness, shape) is set for a given waveguide and each of a plurality of waveguides branched from the waveguide, on the basis of the number of intersections that were counted.
