Multiplexer–Demultiplexer based on nematic liquid crystal photonic crystal fiber coupler

Abstract: 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 −20 dB with great bandwidths of 40 and 24 nm around the wave… Show more

“…Using the finite difference method modal characteristics (confinement loss, dispersion and birefringence) of single core LC filled PCF are discussed in reference [15]. The same group also reported the coupling and polarization characteristics of the similar PCF with dual core [16][17][18]. Coupling and birefringence results obtained from our vector finite element based model qualitatively agree with their reported results.…”

“…Zeonor is used as the background material of the reported RH-CPCF sensor. To compare with recent published articles [22][23][24][25][26][27][28][29][30][31][32][33][34], the proposed RH-CPCF shows the better performance of sensitivity and confinement loss are 76.44%, 77.16%, 73.20% and 2.33 × 10 −03 dB/m, 3.07 × 10 −06 dB/m, 2.84 × 10 −02 dB/m for ethanol, benzene and water respectively at 1 THz frequency. So, this suggested RH-CPCF is highly useful in biomedicine and industrial chemicals research for sensing applications in the terahertz frequency range.…”

“…The first PCF were proposed as an optical waveguide. However, due to the excellent optical performance, it holds many real applications in various areas such as gas sensor [5], chemical sensor [6], pressure sensor [7], salinity and temperature sensor [8], optical multiplexer and demultiplexer [9][10][11], optical power splitter [12], optical filter [13], etc.…”
