The asymmetric quantum dot has permanent electric dipole moments that also interact with light. We derive the density matrix equations for the system including the modification of the electric field and the exciton-plasmon coupling. We emphasize on the effects of the nonlinear optical rectification and controlled optical bistability and analyze these phenomena for different values of the light intensity and different distances between the quantum dot and the metal nanoparticle. We show that when the system is set in a situation where optical bistability can be produced, the optical rectification of the hybrid system is bivalued. We also analyze the slow-down to reach the steady state when the system is driven close and far from the turning points.engjournal articlehttps://doi.org/10.1063/1.5045207https://aip.scitation.org/doi/10.1063/1.5045207open access539.2:620.1530.145535.317.2Optical rectificationElectric dipole momentsOptical bistabilityNanoparticlesPopulation inversionPlasmonicsPlasmonsExcitonsQuantum dotsFísica del estado sólidoÓptica (Física)Óptica física, óptica cuántica2211 Física del Estado Sólido2209.19 Óptica Física2209.19 Óptica física
