Abstract: (717 Views)
Semiconductor nanostructures have been proposed as novel optical switching systems in telecommunication systems due to their unique electrical and optical properties. In this paper, the effect of tunneling on probe field absorption and dispersion for a quantum dot molecule is investigated. The results show that applying voltage gate affects on probe beam propagation, and thus its absorption, dispersion and group velocity. By applying gate voltages, absorption and dispersion may change with the tunneling effect, and light propagation from superluminal to subluminal can be switched.
