Abstract

Phase sensitive analysis of femtosecond pulse propagation in optical fibers employing frequency resolved optical gating (FROG) is presented and compared to numerical simulations employing a modified cubic nonlinear Schrödinger equation (NLSE). Phase information obtained from deconvolution of the experimental traces allows the observation and characterization of specific pulse propagation features as a function of energy and distance. The experimental observation of the phase signature of a soliton during propagation and the phase properties of the soliton self-frequency shift are described and are found to be in remarkable agreement with the simulations.
