Cold and Hot Spots: from Inhibition to Enhancement by Nanoscale Phase Tuning of Optical Nanoantennas
Blascetta, Nicola Palombo; Lombardi, Pietro; Toninelli, Costanza; van Hulst, Niek F. (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 ... -
Enhancing Magnetic Light Emission with All-Dielectric Optical Nanoantennas
Sanz-Paz, Maria; Ernandes, Cyrine; Esparza, Juan Uriel; Burr, Geoffrey W.; van Hulst, Niek F.; Maître, Agnès; Aigouy, Lionel; Gacoin, Thierry; Bonod, Nicolas; Garcia-Parajo, Maria F.; Bidault, Sébastien; Mivelle, Mathieu (ACS, 2018-04-27)
Article
Open AccessElectric and magnetic optical fields carry the same amount of energy. Nevertheless, the efficiency with which matter interacts with electric optical fields is commonly accepted to be at least 4 orders of magnitude higher ... -
Fast photochronoamperometry of photosynthetic complexes for biosensors and electron transport studies
López-Ortiz, Manuel; Zamora, Ricardo A.; Remesh, Vikas; Hu, Chen; Croce, Roberta; van Hulst, Niek F.; Gorostiza, Pau (ACS, 2021-02-16)
Article
Open AccessPhotosynthetic reactions in plants, algae, and cyanobacteria are driven by photosystem I and photosystem II complexes, which specifically reduce or oxidize partner redox biomolecules. Photosynthetic complexes can also bind ... -
Nanoscale mapping and control of antenna-coupling strength for bright single photon sources
Singh, Anshuman; Roque Fernández, Pablo Manuel de; Calbris, Gaëtan; Hugall, James T.; van Hulst, Niek F. (ACS, 2017-03-23)

Open AccessCavity QED is the art of enhancing light-matter interaction of photon emitters in cavities, with opportunities for sensing, quantum information and energy capture technologies. To boost emitter-cavity interaction, i.e. ... -
Phase control of plasmon enhanced two-photon photoluminescence in resonant gold nanoantennas
Remesh, Vikas; Stührenberg, Michael; Saemisch, Lisa; Accanto, Nicolò; van Hulst, Niek F. (AIP, 2018-08-08)
Article
Open AccessPlasmonic nanoantennas emit two-photon photoluminescence, which is much stronger than their second harmonic generation. Unfortunately, luminescence is an incoherent process and therefore generally not explored for nanoscale ... -
Photocurrent-detected 2D electronic spectroscopy reveals ultrafast hole transfer in operating PM6/Y6 organic solar cells
Bolzonello, Luca; Bernal Texca, Francisco Gumaro; Gerling Sarabia, Luis Guillermo; Ockova, Jana; Collini, Elisabetta; Martorell Pena, Jordi; van Hulst, Niek F. (2021-04-29)
Article
Open AccessThe performance of nonfullerene-acceptor-(NFA)-based organic solar cells is rapidly approaching the efficiency of inorganic cells. The chemical versatility of NFAs extends the light-harvesting range to the infrared, while ... -
