Abstract
In this paper,a novel high birefringence Photonic Crystal Fiber (PCF)is proposed and its birefringence,dispersion, nonlinearity,confinement loss and mode field numerically analyzed.The study shows that when its structural parameters are optimized,its birefringence value is 2.36×10-2 ,negative dispersion value -7 740 ps/(km·nm),and the nonlinear coeffi-cient is 56 km-1 ·W-1 ,the corresponding area of mode field 2.17μm2 ,and the confinement loss in the fundamental mode is only 0.10 dB/km at wavelength of 1.55 μm,while its dispersion slope fluctuates between -21.9~-23.5 ps/(km·nm2 ) over the C band.This type of fiber will be widely applied in fiber lasers,fiber amplifiers and optical filters and sensors in the future.关键词
