Abstract

In this letter, we numerically investigate the soliton-effect compression of femtosec- ond optical pulses in highly nonlinear silica-core photonic crystal fiber (HN-PCF) at near-infrared region of the spectrum (specially at 850 nm) using full-vector finite element method and split- step Fourier method. We propose a novel photonic crystal fiber structure featuring a anomalous group velocity dispersion (β2 = −50.698 ps2 /km), small higher-order dispersions and enhanced nonlinearity (γ = 268.4191 w−1 /km) for efficient soliton-effect compression of femtosecond optical pulses. We numerically investigate the effect of the high-order soliton compression of Gaussian pulses in HN-PCF. It shows that high-quality ultrashort optical pulses with little pedestal energy can be obtained.
