Silicon Nanoantenna Mix Arrays for a Trifecta of Quantum Emitter Enhancements
Zhaogang Dong, Sergey Gorelik, Ramón Paniagua-Dominguez +9
Dielectric nanostructures have demonstrated optical antenna effects due to Mie resonances. Preliminary investigations on dielectric nanoantennas have been carried out for a trifect…
Dual-resonance nanostructures for colour down-conversion of colloidal quantum emitters
Son Tung Ha, Emmanuel Lassalle, Xiao Liang +9
Linear colour conversion is a process where an emitter absorbs a photon and then emits another photon with either higher or lower energy, corresponding to up- or down conversion, r…
Large field-of-view and multi-color imaging with GaP quadratic metalenses
Anton V. Baranikov, Egor Khaidarov, Emmanuel Lassalle +5
Metalenses, in order to compete with conventional bulk optics in commercial imaging systems, often require large field of view (FOV) and broadband operation simultaneously. However…
Electrically Tunable Reflective Metasurfaces with Continuous and Full Phase Modulation for High-efficiency Wavefront Control at Visible Frequencies
Parikshit Moitra, Xuewu Xu, Rasna Maruthiyodan Veetil +4
All-dielectric optical metasurfaces can locally control the amplitude and phase of light at the nanoscale, enabling arbitrary wavefront shaping. However, lack of post-fabrication t…
Tunable wavefront control in the visible spectrum using low-loss chalcogenide phase change metasurfaces
Parikshit Moitra, Yunzheng Wang, Xinan Liang +6
All-dielectric metasurfaces provide unique solutions for advanced wavefront manipulation of light with complete control of amplitude and phase at sub-wavelength scales. One limitat…
Hybrid Dielectric-Plasmonic Nanoantenna with Multiresonances for Subwavelength Photon Sources
Pavel A. Dmitriev, Emmanuel Lassalle, Lu Ding +7
The enhancement of the photoluminescence of quantum dots induced by an optical nanoantenna has been studied considerably, but there is still significant interest in optimizing and…
