Continuous wave-controlled shape and chirp oscillations of optical solitons

Abstract

Interactions between solitons and continuous waves (CW) are studied in terms of a perturbation method and systematic numerical simulations as well. The critical dependence of the interactions on the initial phase difference between the pulse and the CW is shown to result in two distinct types of evolution under propagation. Pulse shape and chirp oscillations occur for specific configurations of pulse and CW initial amplitudes and phase difference, while pulse destruction and splitting occurs for other possible configurations. The effect of modulational instability, emerging from the interactions, is also considered.
