Cold and Hot Spots: from Inhibition to Enhancement by Nanoscale Phase Tuning of Optical Nanoantennas
(ACS, 2020-08-17)
Article
Open AccessOptical nanoantennas are well-known for the confinement of light into nanoscale hot spots, suitable for emission enhancement and sensing applications. Here, we show how control of the antenna dimensions allows tuning ... -
Far-field control of nanoscale hotspots by near-field interference
(ACS, 2020-07-31)
Article
Open AccessOptical nanoantennas coherently scatter incident optical radiation, creating a localized electromagnetic near-field imprinted with subwavelength phase distribution, rapidly changing in space. The nanostructuring of phase ... -
Room Temperature Excitation-Emission Spectra of Single LH2 Complexes Show Remarkably Little Variation
(ACS, 2020-03-06)
Article
Open AccessExcitation spectroscopy gives direct insight into the excited state manifold, energy transfer, transient intermediates, vibrations, and so on. Unfortunately, excitation spectroscopy of single molecules under ambient ... -
Ultrafast Stimulated Emission Microscopy of Single Nanocrystals
(AAAS, 2019-12-06)
Article
Open AccessSingle-molecule detection is a powerful method used to distinguish different species and follow time trajectories within the ensemble average. However, such detection capability requires efficient emitters and is prone to ... -
Nanoscale Imaging and Control of hexagonal Boron-Nitride Single Photon Emitters by a Resonant Nano-antenna
(ACS, 2020-02-13)
Article
Open AccessDefect centers in two-dimensional hexagonal boron nitride (hBN) are drawing attention as single-photon emitters with high photostability at room temperature. With their ultrahigh photon-stability, hBN single-photon emitters ... -
Control of Vibronic Transition Rates by Resonant Single-Molecule-Nanoantenna Coupling
(ACS, 2020-05-13)
Article
Open AccessPlasmonic nanostructures dramatically alter the radiative and nonradiative properties of single molecules in their vicinity. This coupling-induced change in decay channels selectively enhances specific vibronic transitions, ... -
Isolating strong nanoantenna-molecule interactions by ensemble-level single-molecule detection
(Royal Society of Chemistry, 2020-01-16)
Article
Open AccessTraditionally, the nanoscale interaction between single photon emitters and plasmonic nanostructures is studied by relying on deterministic, near-perfect, nanoscale-control, either top-down or bottom-up. However, these ... -
Coherent Multiphoton Control of Gallium Phosphide Nanodisk Resonances
(ACS, 2019-09-09)
Article
Open AccessHigh-index dielectric nanoantennas have recently emerged as promising alternatives to plasmonic nanoantennas for concentrating and manipulating light at the nanoscale. For example, gallium phosphide (GaP) nanoantennas ... -
