Experimental Study of Elementary Inter-Modal Nonlinear Interactions in a Long Few-Mode Fiber
07 July 2013
We report the results of an experimental investigation of inter-modal nonlinearities in a 4.7-km few-mode fiber (FMF). Both inter-modal cross-phase modulation (IM-XPM) and inter-modal four-wave mixing (IM-FWM) have been observed between waves separated by a several TeraHertz.
