Abstract
A polarization-maintaining dispersion-compensation microstructure fiber includes an inner core, an air-hole array in areaand an air-hole array in area. The air holes in the areaand 2 air-hole arrays are arranged in square lattice. The air-hole arrays in areasandare dislocated by half-layer along y-direction. In area, 2 air holes in the middle row are omitted to form a solid area as the inner core. 2 outer cores are located in 2 sub-areas of area, and each outer core contains 2 air holes. The long (or short) axes of the inner and outer cores are perpendicular, and the center points of the inner core and the two outer cores are located on the x-axis.
