Modeling Photonic Crystal Fiber for Efficient Soliton-Effect Compression of Femtosecond Optical Pulses at 850 nm

Abstract

In this paper, we numerically investigate the dynamics of soliton-effect compression of femtosecond optical pulses in silica-core photonic crystal fiber (PCF) at 850 nm using both empirical relations method and symmetrized split-step Fourier method. We propose a novel nano-size silica PCF structure featuring a minimum anomalous group velocity dispersion, small higher-order dispersions and enhanced nonlinearity for efficient soliton-effect compression of femtosecond optical pulses with subnanojoule input pulse energies over small distances.
