The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

In the classical world, a beam of light is a smooth, continuous wave. In the quantum realm, however, photons manifest as the discrete constituents (quanta) of light. These photons can be carefully ...

Now researchers at the Massachusetts Institute of Technology have found a way to use terahertz light to watch a superconductor move in a new way. The work, led by MIT physicist Nuh Gedik and MIT ...

A rendering of the metasurface chip in action. When hit with an infrared laser, the microscopic chip converts the incoming light to a higher frequency and sends it out as a narrow beam that can be ...
