Nanophotonics is the science of controlling light on length scales far smaller than the wavelength. Light-matter interaction benefits from confining light to as small a volume as possible, for as long as possible, for which a variety of dielectric and metallic resonator nanostructures have been proposed. However, the smaller the volume into which you shrink light, the faster light leaks away. Very recently the field of extreme nanophotonics emerged, using nanometric metal junction that resonate for about 20 optical cycles to shrink light to 3/105. We combine this approach of plasmonic antennas to photonic microcavities that can imbue plasmonics with high-Q, and thereby sharp, long-lived resonances. I will discuss the surprising physics of these hybrids, their realization, and appli-cations to single-emitter fluorescence and surface-enhanced Ra-man scattering.
