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
