title: Effect of intrapulse stimulated Raman scattering on soliton-effect pulse compression in optical fibers.
abstract: The effect of intrapulse stimulated Raman scattering (ISRS) on the quality of soliton-effect pulse compression is analyzed by solving the generalized nonlinear Schrödinger equation numerically. The results show that ISRS can improve the performance of soliton-effect pulse compressors both qualitatively and quantitatively. The compressed pulse is shorter with a higher peak power when ISRS is taken into account. Furthermore it is pedestal free as it separates from the background. The separation is due to the soliton self-frequency shift initiated by the process of ISRS. It can also be understood in terms of the soliton decay. The optimum fiber length is found to be longer than that expected in the absence of ISRS.
