TWO-DIMENSIONAL PHOTONIC CRYSTAL WITH GEOMETRICALLY ARRAYED LATTICE DEFECTS

摘要

PROBLEM TO BE SOLVED: To provide a two-dimensional photonic crystal having lattice defects having a geometric array formed locally in a periodic array of the two-dimensional photonic crystal.;SOLUTION: The two-dimensional photonic crystal consists of a medium 1 which extends in two dimensions and the other medium 2 which is periodically arrayed in the medium 1 in a square lattice shape and differs in refractive index from the medium 1. The photonic crystal has a triangular array defect 51 formed by locally arraying the medium 2 as a triangular array in the photonic crystal.;COPYRIGHT: (C)2004,JPO
