摘要：
A novel design of Multiplexer-Demultiplexer (MUX-DEMUX) based on index guiding soft glass nematic liquid crystal (NLC) based photonic crystal fiber coupler is proposed and analyzed. The simulation results are obtained using the full vectorial finite difference method as well as the full vectorial finite difference beam propagation method. The numerical results reveal that the proposed MUX-DEMUX of length 3.265 mm can provide low crosstalk better than -20dB with great bandwidths of 40 and 24 nm around the wavelengths of 1.3 and 1.55 mu m, respectively. In addition, the reported MUX-DEMUX has a tolerance of +/- 3% in its length which makes the design more robust to the perturbation introduced during the fabrication process.
