Abstract

The optical bistability (OB) is investigated theoretically in a unidirectional ring cavity containing two-coupled four-level quantum wells (QWs). Manipulating the field, frequency detuning, and the relative phase of the applied fields, can be used to control the OB behaviors. Such a structure may be more practical than those atomic ones because of its more flexible and adjustable properties. The results may be used to optimize the optical switching design..
