“…Solid lines in Figs. 2a and 3 show the characteristics of the corresponding effective refractive index n eff and dispersion D, respectively, computed in (Sobon et al 2014) in the range from 500 nm to 4000 nm. In the first attempt, a triple-pole Lorentz model will be fitted to the aforementioned curves using the Levenberg-Marquardt algorithm executed with no bounds imposed on the Lorentz parameters.…”

“…In the first attempt, a triple-pole Lorentz model will be fitted to the aforementioned curves using the Levenberg-Marquardt algorithm executed with no bounds imposed on the Lorentz parameters. According to (Sobon et al 2014), SC evolves in the considered PCF in the 500-2400 nm range (see Fig. 5 therein), so the fitting has been limited to that range.…”

“…Consequently, if that spectral range was essential for SC Fig. 1 SEM images of a PCF made of PBG-08 glass (Sobon et al 2014) generation, other representation of mode dispersion should be applied instead. It should be noted, however, that the decrease of D with the wavelength usually coincides with the increase of confinement loss (Stepniewski et al 2014), so that the evolution of spectrum does not extend beyond that limit.…”

It is shown in this paper that a finite-difference time-domain method can be successfully applied to rigorous electromagnetic analysis of supercontinuum generation in photonic crystal fibers. Large computational requirements of the method are alleviated by the use of a hybrid procedure where, at first, vector two-dimensional simulation is applied in order to determine mode properties of the fiber. Subsequently, one-dimensional simulation of a pulse propagating in a transmission line filled with effective material is performed. The parameters of the line take into account nonlinear characteristics of the filling material as well as the previously computed mode dispersion. It is depicted that the proposed novel hybrid approach opens the way for rigorous, yet, computationally-efficient modeling of third order nonlinear processes in optically long fibers. The example investigated in this paper shows very promising results as compared with experiments and approximate numerical simulations of a nonlinear Schrodinger equation performed with the aid of the split-step Fourier method.
