Title Controlling the optical bistability in a three-level quantum-dot molecule via gate voltage and indirect incoherent pump field Type of Research Article Keywords optical bistability, three-level quantum-dot molecule, gate voltage, incoherent pump field Abstract Modification of the optical bistability (OB) in an asymmetric double quantum dot (QD) molecule is investigated via interdot tunnel coupling. It is shown that the bistable threshold intensity can efficiently be controlled by tuning the system parameters such as the gate voltage and indirect incoherent pump rate. This may be employed for the development of new types of nanoelectronic devices for realizing switching process.
