Lincoln Laboratory laser communications terminal launches on historic Artemis II moon mission

In 1969, Apollo 11 astronaut Neil Armstrong stepped onto the moon’s surface — a momentous engineering and science feat marked by his iconic words: “That’s one small step for man, one giant leap for mankind.” Now, NASA is making history again. With the successful launch of NASA’s Artemis II mission yesterday, four astronauts are set to become the first […]

New photonic device efficiently beams light into free space

Photonic chips use light to process data instead of electricity, enabling faster communication speeds and greater bandwidth. Most of that light typically stays on the chip, trapped in optical wires, and is difficult to transmit to the outside world in an efficient manner. If a lot of light could be rapidly and precisely beamed off […]
