Sublime Transfer Printing of Three-Dimensional Nanostructure Ensembles
Lei Chen, Hao Wang, Wang Zhang +11
High-resolution three-dimensional (3D) nanostructures for visible-light photon manipulation provide unique and bespoke capabilities in optics and photonics. However subwavelength n…
Encoding orbital angular momentum of light in space with optical catastrophes
Xiaoyan Zhou, John You En Chan, Chia-Te Chang +6
Light beams carrying orbital angular momentum (OAM) possess an unbounded set of orthogonal modes, offering significant potential for optical communication and security. However, ex…
Arbitrary Engineering of Spatial Caustics with 3D-printed Metasurfaces
Xiaoyan Zhou, Hongtao Wang, Shuxi Liu +6
Caustics occur in diverse physical systems, spanning the nano-scale in electron microscopy to astronomical-scale in gravitational lensing. As envelopes of rays, optical caustics re…
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…
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…
Overcoming Van der Waals Forces in reconfigurable nanostructures
Wang Zhang, Hao Wang, Alvin T. L. Tan +11
Reconfigurable metamaterials require constituent nanostructures to demonstrate switching of shapes with external stimuli. For generality, such nanostructures would touch and stick…
Reconfiguring colours of single relief structures by directional stretching
Qifeng Ruan, Wang Zhang, Hao Wang +7
Colour changes can be achieved by straining photonic crystals or gratings embedded in stretchable materials. However, the multiple repeat units and the need for a volumetric assemb…
A Modular Design of Continuously Tunable Full Color Plasmonic Pixels with Broken Rotational Symmetry
Rui Feng, Hao Wang, Yongyin Cao +7
Color tuning is a fascinating and indispensable property in applications such as advanced display, active camouflaging and information encryption. Thus far, a variety of reconfigur…
Schrodinger's Red Pixel by Quasi Bound-State-In-Continuum
Zhaogang Dong, Lei Jin, Soroosh Daqiqeh Rezaei +9
While structural colors are ubiquitous in nature, saturated reds are mysteriously absent. Hence, a longstanding problem is in fabricating nanostructured surfaces that exhibit refle…
High-resolution light field prints by nanoscale 3D printing
John You En Chan, Qifeng Ruan, Menghua Jiang +5
A light field print (LFP) displays three-dimensional (3D) information to the naked-eye observer under ambient white light illumination. Changing perspectives of a 3D image are seen…
Painting with Hue, Saturation, and Brightness Control by Nanoscale 3D Printing
Hao Wang, Qifeng Ruan, Hongtao Wang +7
Varying only the in-plane or out-of-plane dimensions of nanostructures produces a wide range of colourful elements in metasurfaces and thin films. However, achieving shades of grey…
Structural Color 3D Printing By Shrinking Photonic Crystals
Yejing Liu, Hao Wang, Jinfa Ho +9
The rings, spots and stripes found on some butterflies, Pachyrhynchus weevils, and many chameleons are notable examples of natural organisms employing photonic crystals to produce…
