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…
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…
High-order Photonic Cavity Modes Enabled 3D Structural Color
Hailong Liu, Hongtao Wang, Hao Wang +8
It remains a challenge to directly print three-dimensional arbitrary shapes that exhibit structural colors at the micrometer scale. Woodpile photonic crystals (WPCs) fabricated via…
Tunable Mie Resonances in the Visible Spectrum
Li Lu, Zhaogang Dong, Febiana Tijiptoharsono +7
Dielectric optical nanoantennas play an important role in color displays, metasurface holograms, and wavefront shaping applications. They usually exploit Mie resonances as supporte…
Photonic Bound-States-in-the-Continuum Observed with an Electron Nanoprobe
Zhaogang Dong, Zackaria Mahfoud, Ramón Paniagua-Domínguez +8
Bound-states-in-the-continuum (BIC)is a wave-mechanical concept that generates resonances with vanishing spectral linewidths. It has many practical applications in Optics, such as…
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…
