Only this year
Summary
The lecture, taught by Prof. Jean-Jacques Greffet, covers recent developments in the control of light-matter interaction at the nanoscale using resonant structures such as micro-cavities and antennas. It provides the essential theoretical tools to describe the associated phenomena
Content
The first part will introduce fundamental concepts of near-field optics such as evanescent waves and light confinement. The second part will introduce theoretical tools such as integral equations, Green tensor and local density of states. We will then discuss optical resonators, which cover both resonant antennas and cavities and introduce the concept of quasi normal mode. The fourth and fifth parts will be devoted to propagating plasmons and localized plasmons. The sixth part will focus on the control of spontaneous emission and discuss Purcell factor and the weak and strong coupling regimes. We will pay particular attention to clarify what is quantum and what is classical.
