Tunneling Control of Transmission Coefficient and Group Index in a Quantum Dot Nanostructure
We theoretically study the transmission and group index properties of the probe field in a four-level quantum dot molecule. It is found that the tunnel coupling plays a very important role in realizing the transmission coefficient of the probe field. Moreover, the impact of an incoherent pump field...
