Supercontinuum generation in highly nonlinear low-dispersion photonic crystal fiber

We proposed a new structure of highly nonlinear low- dispersion photonic crystal fiber. Numerical results show that the dispersion variation is within ± 0.7 ps·km-1·nm-1 in the C band, and the corresponding nonlinear coefficient is 60.5 60.5 W-1·km-1. With the 6 W peak power of the input pulse, and PCF with 800 m length generates a SC with a spectrum ranging from 1500 to 1800 nm.
