摘要： PROBLEM TO BE SOLVED: To provide an optical branching apparatus that lowers optical loss. SOLUTION: The optical branching apparatus is composed of an input waveguide 1, a mode conversion tapered waveguide 2 connected to the input waveguide 1, and two output waveguides 3, 4 connected to the mode conversion tapered waveguide 2. In the propagation of a light wave from the input waveguide 1 to the mode conversion tapered waveguide 2, the ground mode and the high-order mode of the mode conversion tapered waveguide 2 are excited, with no ground mode dissipated in the structure. In addition, interference fringes by the ground mode and the high-order mode localize its strength in the connecting position with the output waveguides 3, 4 in the mode conversion tapered waveguide 2 in the structure. Thus, the input waveguide 1 and the output waveguides 3, 4 are efficiently coupled with each other, thereby lowering the light wave loss. COPYRIGHT: (C)2006,JPO&NCIPI

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.
