A novel single-polarization single-mode photonic crystal fiber

摘要

A novel single-polarization single-mode (SPSM) photonic crystal fiber (PCF) is proposed and analyzed through a full-vector finite element method (FEM) with anisotropic perfectly matched layer (PML). Numerical results show that the proposed fiber is a low-loss SPSM-PCF within wavelength range from 1370 to 1610nm, in which only the slow-axis mode is guided and the confinement loss is below 0.1dB/km.
