WebbBackground. The scalar version of the SSPROP solves the scalar nonlinear Schrödinger equation: using the symmetrized split-step Fourier method. It allows for almost arbitrary specification of the dispersion and loss, and it includes a simple approximation for the delayed Raman response time and the optical self-steepening effect. http://yuxiqbs.cqvip.com/Qikan/Search/Index?key=S%3dDepartamento%2bde%2bF%c3%adsica
