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…
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…
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…
