Design of High Birefringence with Two Zero Dispersion Wavelength and Highly Nonlinear Hybrid Photonic Crystal Fiber
A hexagonal hybrid photonic crystal fiber (PCF) with elliptical and circular air holes is designed which gives a very large birefringence. The magnitude of birefringence is 12.046 × 10−3 at 1550 nm which is very high and required for optical systems application. The proposed PCF shows zero dispersion wavelengths around 674 nm and 1591 nm and also having a large value of the nonlinear coefficient which is useful for nonlinear optics. In this paper the calculated value of nonlinear coefficient is 0.06147 W−1m−1 at 1550 nm.
