Abstract
Merging the fields of plasmonics and optical solitons attracted a lot of attention in the last decades. Devices supporting plasmon-soliton waves propagating along metal/nonlinear dielectric interfaces may be of interest for sensor applications or for plasmon generation since they allow their in-plane excitation unlike the usual Krestchmann-Raether mounting. The first description of 1D stationary solution composed of a spatial soliton part coupled with a plasmonic wave was given 30 years ago. More recently, several articles have been published on this research topic of plasmon-soliton coupling [1]. Nevertheless, up to now, no experimental results have been published on this issue of plasmon-soliton. The main reason is that for the already proposed structures the required induced nonlinear refractive index change (or peak power) is too high compared to the one attainable for real materials.
