Changing the color of quantum light on an integrated chip

Optical photons are ideal carriers of quantum information. But to work together in a quantum computer or network, they need to have the same color—or frequency—and bandwidth. Changing a photon's frequency requires altering ...

Three-dimensional imaging with optical frequency combs

Holography is a powerful technique of photography of a light field without a lens for 3D imaging and display. Now, scientists at the Max-Planck Institute of Quantum Optics are moving holography forward by implementing it ...

HD video from the moon in near real time

A new optical modem, capable of sending high-definition quality video significantly faster than standard radio frequency systems, is being developed for NASA's Orion spacecraft. The hardware, offered by LGS Innovations, is ...

New device for ultrafast optical communications

A new device invented by engineers at UC Davis could make it much faster to convert pulses of light into electronic signals and back again. The technology could be applied to ultrafast, high-capacity communications, imaging ...

Super-massive black hole inflates giant bubble

Like symbiotic species, a galaxy and its central black hole lead intimately connected lives. The details of this relationship still pose many puzzles for astronomers. Some black holes actively accrete matter. Part of this ...
