Strong Coupling Between Organic Molecules and Plasmonic Nanostructures

Abstract

This chapter introduces the theory behind strong coupling of plasmonic modes, such as surface plasmon polaritons, with electronic transitions that are typical for quantum emitters, such as dye molecules and quantum dots. A brief historical overview of the experimental endeavor of measuring such strong coupling is provided, after which we look more carefully at the dynamics in such systems. We proceed with a more in-depth discussion of strong coupling between emitters and delocalized plasmonic modes, called surface lattice resonances, but not before devoting some space to the ideas and theory behind surface lattice resonances for the readers who might not be familiar with the topic. We end the chapter with an outlook on the potential strong coupling has for new and exciting fundamental phenomena and applications of light on the nanoscale.
