Investigation of optical bistability in a double In_xGa_1−xN/GaN quantum-dot nanostructure via inter-dot tunneling effect

Abstract

In this paper, our aim is to control optical bistability (OB) and optical multistability (OM) in a five-level system designed in a double quantum dot (QD) nanostructure. In a realistic example, this atomic system is created in two semiconductor QDs (${\mathrm{In}}_x{\mathrm{Ga}}_{1-x}\mathrm{N}/\mathrm{GaN}$), owning transfer of carriers via tunneling effect. OB behavior is controlled not only by the inter-dot tunneling effect but also by variation of probe detuning and intensity of the control field. It is demonstrated that voltage-controlled detuning can significantly affect the behavior of OB and OM; therefore, the OM converts to OB by probe detuning and intensity of the control field.
