摘要：
We investigate the optical bistability (OB) behavior in a unidirectional ring cavity containing an asymmetric semiconductor double quantum dot (QD) system that forms a three-level V type system. We apply a probe and a coupling field to the system and it is shown that in the presence of inter-dot tunneling, the bistability of the system can be controlled by amplitude and relative phase of applied fields.
