“TPL” is a well-understood technology for 3D printing extremely small structures. It typically involves focusing a laser at a tiny point within a resin vat, solidifying a very small region. By moving ...

(Nanowerk Spotlight) Optical metasurfaces are sub-wavelength nanopatterned layers that interact strongly with light, thus dramatically altering the light properties over a sub-wavelength thickness.

Design of the laser speckle exposure system. Schematic representation of the laser speckle exposure system, comprising the UV laser, shutter, beam expander, mirror, convex lens, engineering diffuser, ...

The Lawrence Livermore National Laboratory is working on a petawatt-class thulium laser that is said to be 10 times more efficient than the CO2 lasers used in EUV tools and could replace CO2 lasers in ...

What does it take to make your own integrated circuits at home? It’s a question that relatively few intrepid hackers have tried to answer, and the answer is usually something along the lines of “a lot ...

A team of scientists from research center ICFO and photonics materials manufacturer Corning has developed a new method for fabricating anti-reflective (AR) surfaces – achieved through nano-structured ...

Portland, Ore. – A soft-lithography technique that harnesses deoxyribonucleic acid (DNA) as a self-reproducing template is being developed at the Massachusetts Institute of Technology's Supramolecular ...
