摘要： PROBLEM TO BE SOLVED: To provide an optical fiber component having high reliability while avoiding contact with an edge by introducing a buckling structure into a fiber. SOLUTION: The optical component in one embodiment is equipped with a substrate 30 having a V-groove 31, a tape fiber 20 having optical fiber core wires 21, and a lid 10 to fix the coated optical fiber mounted on the V-groove. The optical fiber core wire 21 of the tape fiber 20 is mounted on the V-groove 31 of the substrate 30 and fixed by the lid 10 and is buckled over an edge 40 of the V-groove. In this structure, the optical fiber core wire 21 is separated from the edge of the V-groove, which prevents local force on the fiber core wire at the edge, and therefore, cutting in the optical fiber by external stress such as temperature changes or optical degradation by micro-bent are less caused to improve the reliability of the optical component.

摘要： PROBLEM TO BE SOLVED: To provide a method of properly terminating the excessive power of light in a waveguide type device. SOLUTION: According to an embodiment, the waveguide type device includes a terminal structure filled with a light shielding material to terminate the light from the waveguide end. The terminal structure is formed by forming a groove on an optical waveguide by removing a clad and a core, and filling the groove with a material (light shielding material) which attenuates the intensity of the light. Thus, the light incident to the terminal structure is attenuated by the light shielding material and the effect to other optical devices is suppressed by becoming a cross talk component. Such a terminal structure suppresses not only the effect to the optical devices integrated in the same substrate, but also the effect to other optical devices directly connected to the substrate.

摘要： PROBLEM TO BE SOLVED: To provide an optical waveguide circuit chip which has high mechanical strength in a chip end face by suppressing a warp around the chip end face while maintaining optical characteristics of an optical circuit, with a warp left in a part of the optical circuit, among warps due to difference in a thermal expansion coefficient between a substrate and a pattern layer, for the purpose of solving the following problems of a conventional optical waveguide circuit chip: cracks and fragments are likely to occur in a waveguide part or its end face when a reinforcement plate for thickness adjustment is stuck on the chip, causing a problem in mechanical strength; and since warp is forcedly suppressed by vacuum suction, a stress is imparted to the optical waveguide, which is apt to affect optical characteristics such as a transmission wavelength band or polarization dependency of an optical waveguide circuit. SOLUTION: The optical waveguide circuit chip is characterized in that a groove is formed from an upper clad film to a substrate along the waveguide of an optical input/output waveguide circuit.
