Theoretical Design of Single-Polarization Single-Mode Microstructured Polymer Optical Fibres
-
Abstract
Using the full-vector plane-wave expansion method, a kind of PMMA-based
polarization-maintaining microstructured optical fibre (PM-mPOF) is theoretically studied. Dependence of the cutoff wavelengths of the two
orthogonal polarization states (polarized along the two principal axes
of PM-mPOF) on the structure parameters of the fibre is investigated in
detail. A single-polarization single-mode (SPSM) PM-mPOF working in the
visible region is designed and optimized with the result of the maximum
SPSM bandwidth of 140nm.
