Silica nanochannels with diameters of only 30 nm and an aspect ratio of more than 200 recently were created in silica by researchers from China’s Xi’an Jiaotong University. These nanochannels are, ...

Femtosecond laser writing is a transformative technique that utilises ultrashort laser pulses to locally modify the refractive index of a material, enabling the fabrication of intricate ...

Researchers showed that their optimized direct laser writing approach could create high-resolution line gratings on a glass substrate. These SEM images show line gratings the researchers created using ...

Meanwhile, DLW, based on the interaction between light and matter, is an efficient, contactless, mask free, and depth-resolved micro-patterning technique. It is typically performed by coupling a laser ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

WASHINGTON — Researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. These tiny structures can be used for long-term five ...

A project at Penn State University has taken a step towards environmental sensors better able to detect multiple gas species simultaneously. The new approach exploits advances in laser writing ...

While not the first to be plagued by fine webbing effects spoiling their laser-written structures, Joel K W Yang’s group have been the first to exploit it to achieve feature sizes below 10 nm. “A lot ...

Using a femtosecond laser to write patterns on a lithium niobate crystal has yielded the first evidence for a new optical phenomenon. Physicists at the University of Southampton in the UK and the ...

Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution. Researchers combined laser writing and responsive sensor technologies to ...
