Abstract
A single-core polarization-maintaining dispersion compensation micro-structured optical fiber comprises a fiber core, a first layer of air holes surrounding the fiber core, the cladding defects on the x-axis, the cladding defects on the y-axis, and the cladding. The air holes in the fiber cross section are arranged in the equilateral triangle lattice. Three consecutive air holes are omitted to form a solid area. This solid area is the fiber core. There are two cladding defects along the x-axis. Their centers are respectively located at the two vertices of the hexagon on the x-axis, which is formed by the fourth air hole ring from the core exclusive the central air hole. Each cladding defect along the x-axis contains 7 air holes and goes through from the core by only 1 layer of air holes. There are also two cladding defects along the y-axis.
