摘要：

In this study, the authors propose a novel design of ultra-compact multiplexer-demultiplexer (MUX-DEMUX) based on silica photonic crystal fibre coupler. The suggested design has two large holes infiltrated with nematic liquid crystal of type E7. The reported MUX-DEMUX has short device length of 436 mu m with low crosstalk better than -20 dB with bandwidths of 35 and 10 nm around operating wavelength of 1.3 and 1.55 m, respectively. The simulation results are obtained using full-vectorial finite-difference method together with full-vectorial beam propagation method.
