    • PROBLEM TO BE SOLVED: To provide a photonic crystal fiber which can reduce a connection loss when fusion-spliced to a normal optical fiber. SOLUTION: The photonic crystal fiber 1 is composed of quartz glass, has a core region 11 and a clad region 12 surrounding the core region 11, and has a uniform refractive index distribution along the fiber axis. The clad region 12 has a two-dimensional periodic structure in which high-refractive index regions 13 are periodically arranged in a triangular grating in a low-refractive index background region 14 in a cross section perpendicular to the fiber axis. The core region 11 is in a position of defects of the two-dimensional periodic structure in the center of the cross section (i.e. the absence of a high refractive index region in a certain grating point in the center of the two-dimensional periodic structure), having a higher refractive index than the low-refractive index background region 14. The effective refractive index of a core guided mode may be higher than the refractive index of the low-refractive index background region 14. COPYRIGHT: (C)2011,JPO&INPIT
