摘要：

We reported on a polarization beam splitter based on a novel chalcogenide dualcore photonic crystal fiber. The glass matrix of the optical fiber is Ge10As22Se68. We used computerized numerical control precision drilling methods to manufacture preforms. Then the preform was drawn into an optical fiber with a regular hole structure. The maximum extinction ratio reached -32.76 dB with a 26.27 mm-long optical fiber. Numerical results show that the shortest working length of the designed polarization beam splitter is 636 mu m. In addition, the modeling analysis based on the actual structure shows that the theoretical value is consistent with the measured value.
