High power supercontinuum generation in graded-index multimode fibers

Abstract

Over the years, supercontinuum generation in fibers are studied extensively. Photonic crystal fiber technology detailed these studies by allowing the change of dispersion parameter. Nowadays, multimode fibers attracted huge attention by enabling spatiotemporal nonlinearities and multimodal interactions. Recently, with graded-index multimode fibers, researchers reported new nonlinear dynamics such as cascaded Raman scattering [1], spatiotemporal instability [2,3], self-beam cleaning [4], multimode solitons [5].
