Abstract
The nonlinear pulse propagation in photonic crystal fibers without slowly v arying envelope approximation is studied using an improved variant of first -order wave equation. Supercontinuum generation is shown to be caused by a novel mechanism of spectral broadening through fission of higher-order soli tons into redshifted fundamental solitons and blueshifted nonsolitonic radi ation. Good agreement with experimental observations is found, and subcycle pulse compression is studied.
