Probing Surface-Bound Atoms with Quantum Nanophotonics

Probing quantum-vacuum geometrical effects with cold atoms.

The lateral Casimir-Polder force between an atom and a corrugated surface should allow one to study experimentally nontrivial geometrical effects in the electromagnetic quantum vacuum. Here, we derive the theoretical expression of this force in the scattering approach. We show that large corrections to the "proximity force approximation" could be measured using present-day technology with a Bos...

Surface Plasmonic Fields in NANOPHOTONICS

Surface Plasmonic Fields in NANOPHOTONICS The fi eld of nanophotonics is fi nding myriad applications in information technology, health care, lighting, sensing and national security. This article explores the ultrafast electrodynamics of surface plasmonpolariton fi elds on nanostructured metaldielectric boundaries, and describes how to make a sensor to measure chemical reactions at a surface by...

Probing Quantum Hall State Homogeneity with Surface Waves

Integrated diamond networks for quantum nanophotonics.

We demonstrate an integrated nanophotonic network in diamond, consisting of a ring resonator coupled to an optical waveguide with grating in- and outcouplers. Using a nitrogen-vacancy color center embedded inside the ring resonator as a source of photons, single photon generation and routing at room temperature is observed. Furthermore, we observe a large overall photon extraction efficiency (1...
