Abstract

By numerically solving the generalized nonlinear Schrödinger equation, we show that soliton-effect compression of ultrashort pulses in optical fibers can be significantly improved by use of the combined effect of negative third-order dispersion and Raman self-scattering. The effect of Raman self-scattering leads to redshifting of the pulse spectrum, whereas negative third-order dispersion tends to broaden the redshifted spectrum, which results in a significant increase of both the optimum compression ratio and the peak power of the compressed pulse. We also show that, for a given input pulse, there is an optimum negative third-order dispersion at which the improvement in the pulse compression is maximum and that there exists a range of initial pulse widths only within which can the improvement in pulse compression take place.
