Abstract: | A modal solution approach based on the powerful, finite element method (FEM) using a full-vectorial H-field formulation has been used to determine the single-mode operation of a photonic crystal fiber (PCF). The modal solution
of the fundamental space-filling mode has also been obtained to identify the cutoff conditions of the waveguide modes. The
FEM, with the perfectly matched layer boundary condition, has been developed and employed to characterize the leakage loss
and the differential loss between the polarized modes of a PCF. The design approach for a single-polarization and single-mode
PCF has also been discussed. |
