Optical bistability and multistability in hybrid system

Abstract

In this letter, a comprehensive investigation has been conducted on the optical bistability (OB) and optical multistability (OM) phenomena manifested by transmitted light in a ring cavity consisting of a hybrid system of metal nanoparticle (MNP) and semiconductor quantum dot (SQD). Our study has been primarily devoted to examining the influence of the distance between SQD and MNP, as well as the susceptibilities of the SQD, the MNP, and the hybrid nanostructure as a whole, on the OB and OM traits of the transmitted light. Our discoveries demonstrate that a transition from OB to OM, or vice versa, can be accomplished for a definite distance between MNP and QD. It is our contention that our proposed model may have potential applications in the domain of quantum information processes based on SQD-MNP hybrid systems.
