Abstract: | A novel single-mode single-polarization (SMSP) photonic crystal fibre
has been proposed and analysed based
on the polarization-dependent coupling and absorption effect via a full-vector finite element method with perfectly matched
layers. The numerical results predict that very efficient SMSP operation can
be achieved with both high bandwidth and high extinction ratio at low loss
penalty. Effects of the fibre structural parameters on the SMSP bandwidth
and extinction ratio have been explored, which will provide useful
guide for the design and fabrication of the fibre. The results obtained
will be instructive for the realization of new SMSP fibres with high
performance. |
