Single-molecule fluorescence techniques,, are key for a number of applications, including
DNA sequencing,, molecular and cell biology, and early diagnosis. Unfortunately …

We experimentally demonstrate dramatically enhanced light–matter interaction for
molecules placed inside the nanometer scale gap of a plasmonic waveguide. We observe …

Ways to characterize and control excited states at the single-molecule and atomic levels are
needed to exploit excitation-triggered energy-conversion processes. Here, we present a …

Reproducible confinement of light on the nanoscale is essential for the ability to observe and
control chemical reactions at the single-molecule level. Here we reliably form millions of …

Over the last decade, two fields have dominated the attention of sub-diffraction photonics
research: plasmonics and fluorescence nanoscopy. Nanoscopy based on single-molecule …

The coherent interaction between quantum emitters and photonic modes in cavities
underlies many of the current strategies aiming at generating and controlling photonic …

Plasmonics and photonic crystals are two complementary approaches to tailor single-emitter
fluorescence, using strong local field enhancements near metals on one hand and spatially …

Optical cavities can enhance and control light-matter interactions. This level of control has
recently been extended to the nanoscale with single emitter strong coupling even at room …
