Paper Abstract

We investigate splitting and self-trapping of the femtosecond pulse by nanorods reshaping front at optical radiation propagation in a medium containing gold nanorods. We take into account multi-photon absorption of laser radiation by nanorods, and time-dependent nanorod aspect ratio changing due to their reshaping. On the basis of computer simulation we demonstrate appearance of slowing down soliton and superluminality effect simultaneously for various sub-pulses which form from incident Gaussian un-chirped pulse. These sub-pulses possess chirp and soliton shape which differs from a classical soliton of Schrödinger equation with cubic nonlinearity.
