چکیده انگلیسی
A high birefringence and ultra-high nonlinearity photonic crystal fiber (PCF) is proposed, which is composed of an elliptical As2Se3-doped core and an inner cladding with hexagonal lattice. Optical properties of the PCF are simulated by the full-vector finite element method. The simulation results show that the high birefringence of â¼0.33, ultra-high-nonlinearity coefficient of 300757â¯Wâ1kmâ1 and the low confinement loss can be achieved in the proposed PCF simultaneously at the wavelength of 1.55â¯Î¼m. Furthermore, by comparison with the other two materials (80PbO
- 20Ga2O3, As2S3) filled in the core, the As2Se3-doped PCF is found to have the highest birefringence and nonlinearity due to its higher refractive index and nonlinear refractive index. The flattened dispersion feature, as well as the low confinement loss of the proposed PCF structure make it suitable as a wide range of applications, such as the coherent optical communications, polarization-maintaining and nonlinear optics, etc.
