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 ...

Peripheral photoinhibition (PPI) direct laser writing (DLW) is a lithography technique used to fabricate intricate 3D nanostructures that are widely employed in photonics and electronics. PPI-DLW uses ...

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 ...

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, ...
