Fig. 1: Unusual reaction of an optical solitary wave to an impulse.
From: Unusual impulse-momentum relationship in non-reciprocal light interactions
Left and right columns show the cases of applying an impulse to beam A and B, respectively. a, b Input and output profiles of the solitary wave for an impulse of \(J=-0.02\,{\upmu}{{\rm{m}}}^{-1}\). Black dotted lines denote lateral beam shifts expected by the usual impulse-momentum relationship. c, d present simulated momentum changes for different impulses after a 40-mm-long propagation, as shown by blue solid curves. Blue dashed and red solid lines show the analytic results for the unusual and usual impulse-momentum relationships, respectively
