摘要：
In this paper, the coupling characteristics of a dual-core hybrid plasmonic liquid crystal photonic crystal fiber (PCF) is proposed and analyzed using full-vectorial finite-difference method. The suggested structure has a dual-core filled with nematic liquid crystal (NLC) and separated by a metallic wire. The results show that the two fundamental core modes (even mode and odd mode) have different characteristics through the entire wavelength range due to the NLC infiltration. Moreover, the suggested design can be tuned thermally or by an external electric field. Further, the reported coupler can be used as multiplexer-demultiplexer for wavelengths of 1.3 and 1.55 mu m with a short device length of 753 mu m. Additionally, the suggested design has broad bandwidths of 210 and 190 nm around wavelengths of 1.3 and 1.55 mu m, respectively, with low cross talk better than -20 dB.
