Stimulated Raman Adiabatic Passage (STIRAP) as a Route to Achieving Optical Control in Plasmonics

摘要

Optical properties of ensembles of three-level quantum emitters coupled toplasmonic systems are investigated employing a self-consistent model. It isshown that stimulated Raman adiabatic passage (STIRAP) technique can besuccessfully adopted to control optical properties of hybrid materials withcollective effects present and playing an important role in light-matterinteractions. We consider a core-shell nanowire comprised of a silver core anda shell of coupled quantum emitters and utilize STIRAP scheme to controlscattering efficiency of such a system in a frequency and spatial dependentmanner. After the STIRAP induced population transfer to the final state takesplace, the core-shell nanowire exhibits two sets of Rabi splittings with Fanolineshapes indicating strong interactions between two different atomictransitions driven by plasmon near-fields.
