Abstract

In this paper, the optical bistability in a plasmonic nanoparticle by using the Hydrodynamic model for conduction electrons is investigated. It is shown that the optical bistable threshold, the bistable region and the shape of hysteresis loop are dependent on the permittivity of the surrounding medium, and the composition of plasmonic nanoparticle.
