Impact of the incoherent pumping on the optical properties of a dielectric slab doped with quantum dot nanostructure

• It is found that the transmission and reflection pulse can be controlled via tunnel coupling.
• It is demonstrated that the rate of incoherent pump can control optical filtering at probe detuning.
• It is realized that can be better controlled the optical filtering process in the QD system by using of weak incoherent pump.

In this paper, propagation of an electromagnetic pulse through a dielectric slab doped with a quantum dot nanostructure via electron tunneling has been discussed; moreover the effect of incoherent pump field on the transmission and reflection of pulse in a quantum dot has been theoretically investigated. It is shown that with applying these parameters, the proposed model can be controlled as an all-optical filter which is of great interest in optical communication and quantum information processing.
