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 ...

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 ...
