摘要： PROBLEM TO BE SOLVED: To provide an optical function circuit capable of ensuring propagation light transmissity and extinction ratio so as to be great. SOLUTION: A self-cloning technology is employed to use a three-dimensional photonic crystal for a distribution reflecting mechanism of an optical function circuit (OADM). A selection figure indicates the distribution reflecting mechanism composed of the three-dimensional photonic crystal. Grating constants Lx1, Ly1, Lz1 of the three-dimensional photonic crystal are determined to allow an operational band of the optical function circuit to include a first energy band gap in a point X of the three-dimensional photonic crystal. Thus, transmissivity can be prevented from being reduced by variations in the number of waves of propagation light. Furthermore, the band gap is small, so that it is not necessary to use a resonator structure or the like. Thus, the extinction ratio can be ensured so as to be great. COPYRIGHT: (C)2005,JPO&NCIPI
