Transmission of a Single Plasmon Interacting with Multi-Level Quantum Dots Systems Coupled to Plasmonic Waveguide

We theoretically investigated the transmission properties of a single plasmon interacting with two-level quantum dots (QDs) and a V-type three-level QD, coupled to plasmonic waveguide, respectively. We investigated the transmission of a single plasmon by a system including a V-type three-level QD and compared it with that by a system including only two-level QDs.
