摘要： PROBLEM TO BE SOLVED: To provide a method of properly terminating extra light power in a waveguide type device. SOLUTION: The waveguide type device is equipped with a terminating structure in which a light shielding material is filled for the purpose of terminating light from a waveguide end part. This terminating structure can be formed by forming a groove on the optical waveguide by removing a clad and a core, and filling the groove with a material (light shielding material) for attenuating light intensity. Consequently, light made incident on the terminating structure is attenuated by the light shielding material, suppressing effect on other optical devices caused by becoming a cross talk component. Such terminating structure can suppress effect between optical devices integrated in the same substrate as well as effect on other optical devices directly connected to the substrate.
