Abstract
In this paper, one-stage nematic liquid crystal photonic crystal fiber (NLC-PCF) soliton pulse compressor is proposed and analyzed using full-vectorial finite-element method. The suggested design has high birefringence due to the infiltration of the NLC material. Therefore, it can be used as a soliton pulse compressor for the two polarized modes. The reported NLC-PCF compressor has high compression factor ( $F_{C}$ ) of 10.25 with high compression quality factor ( $Q_{C}$ ) of 0.84 at the operating wavelength of 1.55 μm for the quasi-TE mode with short device length of 76 cm. However, the $F_{C}$ and $Q_{C}$ of the quasi TM mode is equal to 10.93 and 0.66, respectively, at the same device length. The pulse compression through higher order solitons is allowed through controlling the fiber dispersion and nonlinear effects. In addition, greater compression can be achieved with large numbers of soliton order.
