Abstract A Pentagonal Photonic Crystal Fiber (P-PCF) injected with As2 S5 in elliptic core has been propounded by FEM technique. The simulation is carried out by perfectly matched layer using COMSOL Multiphysics software. Several features of the PCF have been analyzed as such nonlinearity, confinement loss, birefringence, effective mode area, power fraction, numerical aperture and dispersion by synthesizing the shape of the cladding holes and the elliptic core. The P-PCF renders a higher nonlinear coefficient of 8000 W−1 km−1 , numerical aperture of 0.44, power fraction of 84% and lower confinement loss of 10−7 at 1.00 μm wavelength. Furthermore, higher birefringence and near zero dispersion are also gained. A perfect geometric fabrication and exclusive properties of chalcogenide glass is used as a core makes the PCF so dynamic in polarization controlling schemes, super continuum systems as well as nonlinear fields. Keywords FEM based PCF · Nonlinearity · High-birefringence · Zero-dispersion · Optical communication · Super-continuum generation

1 Introduction The major progressions in subtle wavelength-division multiplexing networks have changed the optical telecommunication industry radically. At present, photonic crystal fiber (PCF) has achieved tumid alacrity in optical fiber systems because of their inimitable optical features and flexibility in model design. Compared to traditional optical fibers, photonic crystal fibers (PCF) provides a variety of applications and noble landmarks, that allow various modern appliances including nonlinear fiber optics, fiber lasers, supercontinuum generation, soliton transmission and fiber sensors (Huang et al. 2014). Fabrication is done by soft glass material in narrow structured photonic crystal fibers. This type of fibers are configured by inner solid c
