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.

Asymmetric Transmission and Diffraction Engineering in Ultrathin media via Coupled Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Grating‐insulator‐grating coupled crosstalking metasurfaces hosted on a silicon nitride membrane platform for asymmetric control of the diffraction pattern and asymmetric transmission. It is shown that exploiting the interferences of higher diffraction orders between the two metasurfaces and engineering the resulting modes enables AT in such ...

Optical Fiber Meta‐Tips Based on Partial‐Phase Control

open access: yesAdvanced Optical Materials, EarlyView.
Optical fibers working as beam splitters or focusing lens are demonstrated, with the aid of a metasurface integrated on the fiber end facet. Metasurfaces based on meta‐atoms featuring partial control of the phase are considered unleashing their potential.

Numerical Study on the Potential Enhancement of Organic Terahertz Sources through Tilted Pulse Front Pumping

open access: yesAdvanced Photonics Research, EarlyView.
In this article, two individually successful concepts, the tilted pulse‐front pumping technique and organic terahertz crystals for highly efficient THz generation are combined in the framework of numeric calculations resulting in increased conversion efficiency, increased damage threshold, and extended lifespan for ≈2 μm pumping.

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...
