High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see. Extreme ...

Physicists at the Australian National University (ANU) are using nanoparticles to develop new sources of light that will allow us to "peel back the curtain" into the world of extremely small ...

A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...

Doubling up: Georgia Tech researchers Kyu-Tae Lee (left) and Mohammad Taghinejad demonstrate frequency doubling on a slab of titanium dioxide using a red laser to create nonlinear effects with tiny ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Bright squeezed light, exhibiting sub-shot-noise quantum noise combined with significant optical power, is ...
