Single-mode and single-polarization operation of photonic crystal fibers

摘要

A modal solution approach based on the powerful, full-vectorial, H-field based finite element method (FEM) has been used to analyze the single mode operation of a PCF. Modal solutions of the fundamental modes of highly birefringent PCFs have been obtained. The FEM with perfectly matched layer condition has been used to characterize the leakage loss and the differential loss between the polarized modes of PCFs. The design of a single-mode single-polarization PCF has also been proposed.
