摘要：PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical waveguide by which a desired optical circuit characteristic is obtained at high yield. SOLUTION: In the method for manufacturing the optical waveguide 6 which has a structure in which cores 4 and 4 through which light is guided are embedded with a clad 5 which has a refractive index lower than that of the cores 4 and 4, the cores 4 and 4 which become an optical circuit are formed by being irradiated with an excimer laser L1.
