Abstract

The response-function based computational approach to Raman scattering in single-mode optical fibers was introduced, in part, as a method for treating situations in which the spectral distinction between pump and Stokes broke down. This happens, for example, in the case of femtosecond optical pulses whose bandwidth exceeds the bandwidth of X₃. The Raman response function has been used with considerable success to predict the propagation properties of many pulses in the femtosecond regime.^1,2 It is not, however, promoted as an approach for longer pulses. In this paper we report on the use of the Raman response function in predicting the propagation properties of picosecond pulses in optical fibers and discuss the results of a numerical reproduction of the laboratory experiments of Raman scattering reported by Stolen and Johnson.³
