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.
