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…
The height of chitinous ridges alone produces the entire structural colour palette
Hemant Kumar Raut, Qifeng Ruan, Cédric Finet +3
The colourful wings of butterflies result from the interaction between light and the intricate chitinous nanostructures on butterflies' scales. This study demonstrates that just by…
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…
