Transmission and reflection properties of incident pulse in a dielectric slab doped with quantum dot

In this paper, transmission and reflection properties of incident pulse in a dielectric slab which doped by quantum dot nanostructure via electron tunneling is studied. It is shown that by using the electron tunneling in a quantum dot, the transmission and reflection coefficients can be controlled at different wavelengths. Therefore, this model can be used as an all-optical filter which is suitable for next generation of all optical communication systems.
