Scientists have achieved a major step toward chip-scale ultraviolet light by converting red light into powerful UV within a ...

A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical ...

Ultraviolet light that fits on a chip 'Sidewall-poled' lithium niobate device paves way for compact UV sources. (Nanowerk News) Ultraviolet light, beyond its natural ...

Ultraviolet light, beyond its natural abundance from the sun, is used in countless modern applications, from disinfection, to fluorescence of ...

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see. Extreme ...

Using two optical frequency combs and a photon counter, the experiments open up exciting prospects for conducting dual-comb spectroscopy in low-light conditions and they pave the way for novel ...

A kilogram of iron sulfate costs pennies. A kilogram of platinum costs tens of thousands of dollars. Both metals can help ...

(Nanowerk News) In a recent publication in Nature ("Near-ultraviolet photon-counting dual-comb spectroscopy"), researchers at the Max Born Institute (MBI) in Berlin, Germany, and at Max-Planck ...
