Highly Nonlinear and Highly Birefringent Hybrid Photonic Crystal Fiber

In this paper, an optimal plan of hybrid photonic crystal fiber (HyPCF) possessing the nature of high non linearity, ultra-high birefringence and negative chromatic dispersion has been recommended. Simulation results demonstrate that the proposed PCF simultaneously contributes a high non-linear coefficient of 50 W^-1km^-1, a high birefringence of 2.15×10^-2 and a negative chromatic dispersion of -159.2 ps/(nm.km) at the operating wavelength of 1.55 μm. To reproduce the fiber structure, The Finite Element Method (FEM) having the orientation of only circular air holes is utilized. The proposed PCF may be employed in numerous nonlinear applications, for example, four-wave blending, sensing applications and so on.
