Switching from optical bistability to multistability in a coupled semiconductor double-quantum-dot nanostructure

摘要

We investigate the optical bistability (OB) and multistability in a coupled semiconductor double-quantum-dot nanostructure inside an optical ring cavity. It is found that the transition from OB to multistability or vice versa can be easily controlled via properly adjusting the corresponding parameters of the system. Our scheme opens the possibility to optimize and control all optical switching and all optical storage devices in a coupled semiconductor double-quantum-dot nanostructure.
