Ultra-thin lithium niobate metalenses with engineered nanostructures can halve the wavelength of incident light, converting infrared (800 nm) to visible (400 nm) while focusing it.

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

The study addresses key limitations of top-down fabrication techniques for lithium niobate, which are constrained by the material’s chemical inertness. The authors present a scalable, cost-efficient ...

There is a sharp medium absorption peaks around 1078 cm-1, which is due to the vibrations of the lithium niobate crystal lattice. The results of FTIR analysis were good agreement with XRD results.

It is also much more cost-effective and faster to fabricate than other lithium niobate miniaturised optical devices. Ultra-thin lenses that generate new light. Using this technique, the ETH ...

For example, the spectrum of lithium hydride showed no peaks at 523 cm−1 (characteristic of Li 2 O) or in the 250–350 cm-1 range (attributed to LiOH). This confirmed that the oxygen- and ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240139, discusses ferroelectric domain engineering of Lithium Niobate.

Swiss photonics startup Lightium AG wants to help data center operators reduce their energy consumption while increasing performance after closing on a $7 million seed funding round.Today’s roun ...

Peak Energy, an energy-storage startup, received $55 million in funding to scale up production of sodium-ion batteries that the company is positioning as an alternative to the widely used lithium ...

Glasses coated in a lithium compound could one day allow wearers to see clearly in the dark. For more than a decade, researchers have been searching for the best lightweight material that can ...
