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

TL;DR

This paper theoretically examines how a single plasmon transmits through systems with multi-level quantum dots coupled to a plasmonic waveguide, comparing two-level and three-level quantum dot configurations.

Contribution

It provides a comparative analysis of plasmon transmission in systems with two-level and V-type three-level quantum dots coupled to a plasmonic waveguide.

Findings

Transmission differs significantly between two-level and three-level QD systems.

The presence of a V-type three-level QD alters the transmission spectrum.

Theoretical insights into plasmon-QD interactions in waveguide systems.

Abstract

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.
