Neural network enabled wide field-of-view imaging with hyperbolic metalenses
Joel Yeo, Deepak K. Sharma, Saurabh Srivastava +8
The ultrathin form factor of metalenses makes them highly appealing for novel sensing and imaging applications. Amongst the various phase profiles, the hyperbolic metalens stands o…
EigenCWD: a spatially-varying deconvolution algorithm for single metalens imaging
Joel Yeo, Duane Loh, Ramon Paniagua-Dominguez +1
The miniaturization of optics through the use of two-dimensional metalenses has enabled novel applications in imaging. To date, single-lens imaging remains the most common configur…
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…
Near-Unity Emitting, Widely Tailorable and Stable Exciton Concentrators Built from Doubly Gradient 2D Semiconductor Nanoplatelets
Xiao Liang, Emek G. Durmusoglu, Maria Lunina +11
The strength of electrostatic interactions (EI) between electrons and holes within semiconductor nanocrystals profoundly impact the performance of their optoelectronic systems, and…
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…
