Mass manufacturing of metasurfaces

The mass production of flat optical devices with sub-wavelength structures could soon be a reality, thanks to a metasurface fabrication technique developed by researchers at A*STAR.

Structural colors, without the shimmer

Structural colors, like those found in some butterflies' wings, birds' feathers and beetles' backs, resist fading because they don't absorb light like dyes and pigments. However, the iridescence that enhances their beauty ...

New computational technique advances color 3-D printing process

Working with researchers at Zhejiang University in China, Changxi Zheng, assistant professor of computer science at Columbia Engineering, has developed a technique that enables hydrographic printing, a widely used industrial ...

New LED packaging technology improves performance

(Phys.org)—Many researchers have reported improvements in LED technology by enhancing the properties of the LED itself. But the packaging that secures and protects the LED also impacts its overall performance. In a new ...

Kyocera develops world's fastest 300dpi inkjet printhead

Kyocera Corporation today announced that it has developed a new 300 dots-per-inch (dpi) inkjet printhead -- a key component for commercial inkjet printers -- which enables simultaneous two-color printing with just one printhead. ...
