A theoretical study of quantum coherence and plasmon-enhanced diffraction in practical hybrid systems including semiconductor quantum dots and metallic nanoparticles

Zeynab Maleki, Tayebeh Naseri

Abstract In this work, we theoretically study a novel strategy for electromagnetically induced gratings in a complex hybrid system consisting of semiconductor quantum dots (SQDs) and metallic nanoparticles (MNPs). The plasmonic resonances of MNPs and the quantum coherence of SQDs enable the generation of unique optical phenomena such as electromagnetically induced transparency via interactions with light. Through surface plasmon interactions and quantum dot interdot tunneling, the modification of light diffraction efficiency into higher orders is achievable. Doppler broadening and nonlocality are included in the model to offer a more realistic picture of the system’s behavior in real-world scenarios. Our proposed model shows significant promise for applications in sensing technologies and nanophotonics, where it has the potential to enhance sensitivity and improve the performance of optical devices.

Optical bistability of a plexcitonic system consisting of a quantum dot near a metallic nanorod

Tayebeh Naseri, Nader Daneshfar

Optical response of a complex nanodimer comprising a semiconductor quantum dot via Coulomb interaction to a metal nanorod is analyzed theoretically. Optical bistability (OB) behavior of a coherently coupled exciton-plasmon (plexcitonic) hybrid system under a laser field is investigated. The bistable exciton population in a hybrid metal–semiconductor nanodimer response is shown, and it could be pointed out that OB behavior is strongly influenced by various parameters such as size of metal nanoparticle, interparticle distance as well as intensity of probe laser field. We show that OB can be observed for a plexcitonic system and depends strongly on the type of the metals which are good candidates for plasmonic applications. The numerical calculations show the gold nanorod exhibits significant optical bistability. The result promises various applications in the field of all-optical information processing at the nanoscale, the most basic of them being the optical switching, optical memory, optical transistor and optical logic.
