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. So ...

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...

Researchers develop a highly efficient method to provide coherent light of any wavelength from visible to mid-infrared with a single tiny device. (Nanowerk News) Focused laser-like light that covers a ...

A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

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 ...

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 ...

I guess it's like how we use the square root of minus one to solve various equations. It sounda impossible but actually works! Click to expand... Sort've, but I don't think they're going into the ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...
