How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

In a potential breakthrough in the field of photonics, a team of researchers reports they have successfully manipulated light at the sub-wavelength scale. Previously thought to be impossible, the ...

New York, NY—November 22, 2021—Over the past several decades, researchers have moved from using electric currents to manipulating light waves in the near-infrared range for telecommunications ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...

Scientists in Switzerland have developed an ultra-thin metalens that converts invisible infrared light into visible light by halving its wavelength, using nanoscale patterns stamped into a special ...

Photons are odd little beasts. They can act like waves. They can act like particles. They are teeny tiny messengers of force. They are carriers of energy. If you're enjoying this article, consider ...
