Experimental demonstration of plasmon-soliton waves
Résumé
We report the experimental observation of plasmon-soliton coupling. The demonstration is performed in a chalcogenide- based four-layer planar geometry designed to limit plasmon propagation losses while exhibiting efficient Kerr self-focusing at moderate power. The observations reveal a strongly enhanced self-focusing undergone by a self-trapped beam propagating inside the structure. As expected, only TM polarized waves exhibit such a behavior. Different experimental arrangements are tested that unambiguously reveal the nonlinear plasmon-soliton coupling which is corroborated by numerical simulations
