Abstract

Control of light–matter coupling at the quantum level is an enabling
techniques for many emerging quantum technologies. This tutorial
describes recent advances in achieving efficient coupling of light with a
single molecule using an optical Fabry–Perot microcavity. We
demonstrate that the efficient cavity-molecule coupling converts the
molecule to an effective two-level system. In this regime, a single
molecule can act as a nearly perfect reflecting mirror and exhibits
optical nonlinearity at the ultimate level of single photons.
