Abstract: A dispersion-compensation microstructure fiber uses pure silica glass as the background material. It includes the core, the first-type defects, the second-type defects and the cladding. The air holes in the fiber cross section are arranged in the equilateral triangle lattice with the same adjacent air-hole to air-hole spacing. The core is formed by omitting 1 air hole.
