Abstract
In this letter, a numerical investigation of the Carbon disulfide (\(CS_2\)) embedded photonic crystal fiber has been reported. Numerical results incurred by using finite element method. A circular perfectly matched layer is used to simulate the design. It indicates high Kerr nonlinearity of 13,667 \(\hbox {W}^{-1}\,\hbox {km}^{-1}\) at the operating wavelength \(\lambda\) = 1000 nm. In addition, effective mode area, confinement factor, numerical aperture, power fraction, dispersion and V-parameter have been also studied. Geometric parameters have been also tuned to observe optical characteristics over the specified domain of operating wavelength. The model shows ultrahigh negative dispersion profile of − 254.67 ps/(nm km) at \(\lambda\) = 1000 nm. Therefore excellent optical performances of the suggested model enables it to be used in parametric amplification, polarization maintaining nonlinear signal processing, optical nonlinear sensor, super-continuum spectrum generation, optical coherence tomography and so on.
