The behavior of optical bistability in triple quantum dot nanostructure using double tunnel coupling inside a unidirectional ring cavity is investigated. Also, the linear and nonlinear absorption of the system are investigated. The double tunneling between the quantum dots can change the absorption of the system. The threshold of OB can be controlled by the intensity of the double tunneling and the detuning of probe field. This may be employed for the development of new types of nanoelectronic devices for realizing switching process.
