Study suggests that silicon could be a photonics game-changer

New research from the University of Surrey has shown that silicon could be one of the most powerful materials for photonic informational manipulation—opening up new possibilities for the production of lasers and displays.

Twistoptics—A new way to control optical nonlinearity

Nonlinear optics, a study of how light interacts with matter, is critical to many photonic applications, from the green laser pointers we're all familiar with to intense broadband (white) light sources for quantum photonics ...

NIST tests underscore potential hazards of green laser pointers

Using a low-cost apparatus designed to quickly and accurately measure the properties of handheld laser devices, National Institute of Standards and Technology (NIST) researchers tested 122 laser pointers and found that nearly ...

Nanoscale nonlinear light source created

Not long after the development of the first laser in 1960 scientists discovered that shining a beam through certain crystals produced light of a different color; more specifically, it produced light of exactly twice the frequency ...

Tiny lasers plug the 'green gap'

( -- Compact lasers which can work in formerly inaccessible parts of the spectrum and are suitable for mass production are now within reach.
