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…
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…
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…
Full Geometric Control of Hidden Color Information in Diffraction Gratings under Angled White Light Illumination
John You En Chan, Qifeng Ruan, Hongtao Wang +5
Under white light illumination, gratings produce an angular distribution of wavelengths dependent on the diffraction order and geometric parameters. However, previous studies of gr…
