Stability of Spatiotemporal Soliton in Multimode Fiber with Optically Induced Temporal Potential

Abstract

We investigate the soliton stability in multimode fiber with an optically induced temporal potential (TP). The soliton experiences a cross-phase-modulation-induced TP when co-propagating with a pump pulse. While without the TP both the spatiotemporal soliton and continuous wave are stable, the TP makes only the spatiotemporal soliton stationary and stable.
