Mesures de l'effet de Kerr dans des guides plans par analyse de faisceaux auto-pièges

2017

International audience; Nous présentons une nouvelle technique expérimentale basée sur l'analyse de faisceaux auto-piégés pour mesurer les non-linéarités Kerr dans des guides plans. Cette technique est appliquée pour analyser les propriétés non linéaires de guides constitués de verres de chalcogénure Ge-Sb-Se qui possèdent un effet Kerr autorisant la formation de solitons spatiaux. Les caractéristiques optiques linéaires et non linéaires de ces structures sont étudiées à 1550 nm en régime femtoseconde. Les coefficients non linéaires obtenus par la technique proposée sont en accord avec les valeurs publiées dans la littérature.

Experimental demonstration and numerical study of plasmon-soliton waves

2019

Merging the fields of plasmonics and nonlinear optics authorizes a variety of fascinating and original physical phenomena. In this work, we specifically study the combination of the strong light confinement ability of surface plasmon polaritons (SPP) with the beam self-trapping effect in a nonlinear optical Kerr medium. Although this idea of plasmon-soliton has been the subject of numerous theoretical papers since the eighties [1–4], up to now, no experimental evidence had been revealed yet. In the present study, a proper structure (Fig. 1a) has been designed and fabricated allowing the first experimental demonstration of these hybrid nonlinear waves merging spatial solitons and SPP. To be …
