Silicon Nitride Metalens for Optical Imaging

open access: yes, 2018
We report an ultrathin silicon nitride metalens for optical imaging. The meta-surface of silicon nitride provides the full phase delay in a broad range of visible wavelengths.

Synthetic aperture metalens

open access: yesPhotonics Research, 2021
Metalenses are ultrathin optical elements that can focus light using densely arranged subwavelength structures. Due to their minimal form factor, they have been considered promising for imaging applications that require extreme system size, weight, and power, such as in consumer electronics and remote sensing. However, as a major impediment prohibiting

Wärmeträgerflüssigkeiten als Co‐Diluenten in lokal hochkonzentrierten Elektrolyten für schnellladefähige Lithium‐Metall‐Batterien mit erhöhter Sicherheit

open access: yesAngewandte Chemie, EarlyView.
Zwei fluorierte Ether aus dem Bereich der Wärmeträgerflüssigkeiten werden als Co‐Diluenten in lokal hochkonzentrierten Elektrolyten für lithiummetallbasierte Batterien eingesetzt. Die ternäre Diluentenmischung erhöht die Ionenmobilität, senkt die Überspannung und verbessert so coulombische Effizienz und Lebensdauer der Zelle bei hohen Stromdichten, was

A Metalens with a Near-Unity Numerical Aperture [PDF]

open access: yesNano Letters, 2018
The numerical aperture (NA) of a lens determines its ability to focus light and its resolving capability. Having a large NA is a very desirable quality for applications requiring small light-matter interaction volumes or large angular collections. Traditionally, a large NA lens based on light refraction requires precision bulk optics that ends up being
