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.
