Universal triangular spectra in parametrically-driven systems

Akhmediev, Nail; Ankiewicz, Adrian; Soto-Crespo, J. M.; Dudley, John M.


We analyse triangular spectra that appear in many branches of physics that deal with parametrically-driven systems, and give a simple theoretical analysis for them in terms of the nonlinear dynamics of multimode fields. Such spectra appear universally as a result of an exponential decay of the nonlinearly generated frequency modes of many parametrically-driven systems, and have been confirmed by recent observations of noise-driven supercontinuum generation in optical fibers. We demonstrate that...[Show more]
