Broadband Angular Selectivity of Light at the Nanoscale: Progress, Applications and Outlook
Yichen Shen, Chia Wei Hsu, Yi Xiang Yeng +2
Humankind has long endeavored to control the propagation direction of light. Since time immemorial, shades, lenses and mirrors have been used to control the flow of light. In moder…
Substrate-Independent Light Confinement in Bioinspired All-Dielectric Surface Resonators
Emma C. Regan, Yichen Shen, Josue J. Lopez +4
Traditionally, photonic crystal slabs can support resonances that are strongly confined to the slab but also couple to external radiation. However, when a photonic crystal slab is…
Air-compatible Broadband Angular Selective Material Systems
Yichen Shen, Chia-Wei Hsu, John D Joannopoulos +1
An optical broadband angular selective filter achieved by stacking of one-dimensional photonic crystals has promising potential in various applications. In this report, we demonstr…
