Self‐Assembling Cracks to Fabricate Antireflective Antifogging Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A multifunctional optical device combining antireflective and photothermal antifogging properties is developed by leveraging crack formation in colloidal films. Plasmonic nanoparticle arrays enable localized heating under illumination, while a mesoporous silica coating provides antireflection and water repellency.

Mimicking Symmetry‐Breaking Einstein Ring by Optical Lens

open access: yesAdvanced Photonics Research, EarlyView.
This article uses an optical lens to emulate the gravitational lensing effect and observe the Einstein ring (ER) patterns. The symmetry‐breaking ER, i.e., Einstein cross, is observed utilizing a rotation‐symmetry‐breaking hemi‐ellipsoid lens. Deformed Einstein cross patterns induced by noncollinearly alignment of the light source–lens–observer are ...
