A novel single-polarization single-mode photonic crystal fiber with circular and elliptical air-holes arrays

Abstract

A novel single-polarization single-mode photonic crystal fiber (SPSM-PCF) with circular and elliptical air-holes is proposed. The characteristics of the proposed SPSM-PCF are investigated by using a full-vector finite element method (FEM) with perfect matched layer (PML) boundary conditions. The results show that the SPSM operation is achieved with wider band, and the total dispersion profile of the SPSM-PCF is dispersion-flattened from 1.193 μm to 1.384 μm. This dispersion property makes the proposed SPSM-PCF useful for various applications, such as optical transmission and dispersion compensation for conventional fiber at long wavelength band with 500 nm negative dispersion region. It indicates that this is a good solution to realize broadband SPSM operation.
