The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence ...

Image showing gold contacts where we bias each laser with DC current. Light is out-coupled from the racetracks using the directional-coupler waveguides along the straight section of either racetrack.

Light is quietly becoming the new language of brain technology. Instead of thick wires and skull-penetrating electrodes, a new generation of implants uses tiny LEDs and optical sensors to send ...
