Generation of few-cycle laser pulses using a photonic quasi-crystal fiber

Abstract

We explore the optical properties of a proposed solid-core photonic quasi-crystal fiber (SC-PQF) of 10-fold for the wavelengths from 300 to 1100 nm. The proposed SC-PQF exhibits a admissible low dispersion of −8.6481 ps2 /km, a third order dispersion of 0.00415 ps3 /km and a large nonlinearity of 1684 W−1 km−1 at 450 nm, which turn out to be the desired optical properties for generating the few-cycle laser pulses. By exploiting these optical properties, we numerically demonstrate the generation of few-cycle laser pulses at 450 nm wavelength by means of higher-order soliton effect compression.
