Abstract
We propose a novel of photonic crystal fiber (PCF) with low dispersion high birefringence for four wave mixing. This fiber is composed of a solid silica core and a cladding with squeezed-hexagonal-lattice circular air-holes along the fiber length. Dispersion and birefringence are investigated simultaneously by using the full vectorial finite element method. Numerical results show the proposed fiber possesses the property of low-dispersion and high-birefringence, with the result of the total dispersion being within ±5 ps•nm-1km-1 over ultra broad wavelength range from 1360 to 1670 nm and the corresponding high birefringence being about 1.5×10-2 at 1550 nm. Furthermore, the nonlinear coefficient of the proposed fiber is also numerically analyzed, and present high nonlinear effects. Therefore, high birefringence, low flattened dispersion and high nonlinear effects are combined in the proposed PCF perfectly, which has the great significance for the four-wave mixing.
