摘要：

A highly birefringent hybrid cladding photonic crystal fiber (PCF) is proposed in this article. The guiding properties of the proposed PCF are numerically investigated using the finite element method (FEM). This fiber exhibits very high birefringence in the order of 10(-2) at communication wavelengths. In addition, low confinement loss of 6.1 x 10(-3) dB/km, lower negative dispersion of - 274.5 ps/nm/km and higher nonlinearity of 76.41 W-1 km(-1) is achieved at the same wavelengths compared with the exist literature. The proposed simple cladding structure is easy for fabrication. Moreover, effective mode area and nonlinear coefficient are analyzed and optimized. The proposed fiber can prove its applications in sensing, telecommunication and non-linear technologies.
