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…
3D Printed Multilayer Structures for High Numerical Aperture Achromatic Metalenses
Cheng-Feng Pan, Hao Wang, Hongtao Wang +8
Flat optics consisting of nanostructures of high-refractive-index materials produce lenses with thin form factors that tend to operate only at specific wavelengths. Recent attempts…
Multi-level Optical Switching by Amorphization in Single- and Multi- Phase Change Material Structures
Simon Wredh, Yunzheng Wang, Joel K. W. Yang +1
The optical properties of phase-change materials (PCM) can be tuned to multiple levels by controlling the transition between their amorphous and crystalline phases. In multi-materi…
Colorful Optical Vortices with White Light Illumination
Hongtao Wang, Hao Wang, Qifeng Ruan +8
The orbital angular momentum (OAM) of light holds great promise for applications in optical communication, super-resolution imaging, and high-dimensional quantum computing. However…
Tri-Functional Metasurface for Phase, Amplitude, and Luminescence Control
Soroosh Daqiqeh Rezaei, Zhaogang Dong, Hao Wang +7
In optical anti-counterfeiting, several distinct optically variable devices (OVDs) are often concurrently employed to compensate for the insufficient security level of constituent…
Miniaturizing Color-Sensitive Photodetectors via Hybrid Nanoantennas towards Sub-micron Dimensions
Jinfa Ho, Zhaogang Dong, Hai Sheng Leong +10
Digital camera sensors utilize color filters on photodiodes to achieve color selectivity. As color filters and photosensitive silicon layers are separate elements, these sensors su…
