Abstract

We theoretically investigate the nonlinear propagation of femtosecond pulses in liquid-core photonic crystal fibers filled with CS 2 . The effect of slow nonlinearity due to reorientational contribution of liquid molecules on broadband supercontinuum generation in the femtosecond regime is studied using an appropriately modified nonlinear Schrödinger equation. To analyze the quality of the pulse, we perform the stability analysis and study coherence of supercontinuum pulse numerically. We show that the response of the slow nonlinearity not only enhances broadening of the pulse and changes the dynamics of the generated solitons, but also increases coherence of the pulse.
