Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...

Rocket Lab said its acquisition of OSI will position the company to deliver critical defense capabilities to the PWSA and the ...

In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

Low-power optical device achieves around 100 times amplification using just a couple of hundred milliwatts of input power ...

WASHINGTON — The Air Force Research Laboratory has awarded BlackSky a contract worth up to $99 million to develop a large optical imaging payload intended for future space-based intelligence systems.

A translator for optical cross-links in orbit and a Link-16 radio have been added to the list of possible demonstrations and experiments planned for the Space Development Agency’s (SDA) next round of ...
