General theory and observation of Cherenkov radiation induced by multimode solitons
Abstract
The multifaceted nature of nonlinear multimode optical fibers has provided a fertile ground for observing novel physical effects otherwise impossible in single-mode setting. The authors present a theoretical and experimental study, providing a comprehensive theory capable of explaining the distinct nature of wideband Cherenkov radiation produced during multimode soliton fission events.
