Theoretical Investigation of Photonic Crystal Fiber with Highly Nonlinear and Birefringent
According to the full-vector finite element method, a new highly nonlinear and birefringence photonic crystal fiber (PCF) with zero-dispersion at wavelength of 1550 nm is designed. The effective refractive index, effective mode area, birefringence, nonlinear coefficient and dispersion characteristics of the PCF are analyzed. Simulation results show that birefringence of the PCF is 4.049×10-3, and nonlinear coefficient reaches 28.4 km-1·W-1 at wavelength of 1550 nm, which are obtained under the condition of cladding air hole pitch size of 1.6 μm, large air hole diameter of 1.4 μm and small air hole diameter of 0.74 μm and 0.76 μm respectively. The PCF has very broad prospect of application in 1550 nm communication band.
