Optical Susceptibility of Hybrid Semiconductor Quantum Dot-Metallic Nano Ellipsoid System Under the Effect of the Exciton-Plasmon Coupling Field Interaction

Abstract

We examine the optical susceptibility of the semiconductor quantum dot-metallic nano ellipsoid system under the effect of the exciton-plasmon coupling field. Also, we determine the optical susceptibility for the semiconductor quantum dot and the three metallic nano ellipsoids under the responses to the total effect of the three applied electromagnetic fields. The phenomena of Fano-resonance with amplification and Autler-Town doublet peaks are obtained and discussed. The phenomena of Fano-resonances and Autler-Town doublet peaks can be controlled by varying the depolarization factor of nano ellipsoid, semi-axes, and other parameters in a hybrid system.
