Highly Nonlinear Photonic Crystal Fibers with Ultra-flattened Chromatic Dispersion and Low Confinement Loss
A novel design of Photonic Crystal Fiber (PCF) was present in order to simultaneously achieve high nonlinearity, ultra-flattened dispersion, and low confinement loss. The software COMSOL based on finite element method with anisotropic perfectly matched layers is used to analyze the effective mode area, dispersion properties, and confinement loss of PCF with eight-ring air holes. Numerical results show that a small effective mode area corresponding to a high nonlinear coefficient of the order 36.2 W-1·km-1 at 1.55 μm wavelength is obtained. Moreover, ultra-flattened dispersion of (0.3±0.3)ps/(nm·km) is also obtained over 330 nm bandwidth from 1.37 μm to 1.70 μm with low confinement losses less than 0.1 dB/km within the band of 1.37 μm to 1.62 μm.
