Demonstrated the similarity to Lorentzian-profile solitons.
Abstract
We found an amazingly simple general "all-band" intensity profile of bandgap (Bragg) solitons for arbitrary parameters of spatially-periodic nonlinear systems, similar to those of multi-frequency stimulated Raman scattering, in particular the so called Lorentzian-profile solitons. We also found nonlinear eigen-modes of such system that propagate without energy exchange between waves.
