摘要

A new kind of single-polarization photonic crystal fiber (PCF) is proposed.Two kinds of multi-component glasses and the air are selected as working materials.Through using the full vector finite element method (FEM) and the perfectly matched layers (PML), the polarization-maintaining characteristic and the confinement loss of the fiber are analyzed, respectively.In addition, the single-polarization region of the fiber around 1.55 μm is discussed.Numerical simulations show that the fiber maintains single-polarization operation within the wavelength range of 1.421-1.696 μm.The birefringence can reach 6.988 × 10-3, and the confinement loss is as low as 0.012 dB/m when 7 layers of ring holes are arranged in the cladding at λ=1.55 μm.
