Determination of liquid crystal filled photonic crystal fiber parameters and nonlinear effects in supercontinuum generation

摘要

We investigate a linear light propagation mechanism in the photonic crystal fibers infiltrated with nematic liquid crystals which is used for supercontinuum generation application. PCF core region consists of soft glass and has nematic liquid crystal filled holes in the cladding region. Using the designed hexagonal solid core liquid crystal PCF, the wavelength dependent fundamental optical characteristics of single mode photonic crystal fibers (SMPCFs) such as birefringence, effective area, confinement loss and dispersion are numerically investigate. Coding and simulation of the problem have been done using MATLAB and COMSOL softwares. The effects of fiber bragg grating in liquid crystal filled photonic crystal leading to supercontinuum generation are discussed here.
