Abstract
Summary form only given. Conventionally dispersive wave (DW) emission in nonlinear fiber optics is described in the time-domain as the resonant amplification of a linear wave propagating in-phase with a soliton pump [1]. Recently, however, a complementary frequency-domain description has been presented, which identifies the nonlinear origins of the process as phasematched cascaded four-wave mixing [2]. This new theory predicts that a pump in the normal dispersion regime (NDR) can transfer energy to a DW propagating in the anomalous dispersion regime (ADR) via exactly the same mechanism by which a pump in the ADR produces a conventional DW in the NDR. Here we use numerical simulations and direct experiments to verify this prediction [3].
