New record: 3-D-printed optical-electronic integration

Optoelectronic integration offers a promising strategy to simultaneously obtain the merits of electrons and photons when they serve as information carriers, including high-density communication and high-speed information ...

NASA demos CubeSat laser communications capability

Two NASA CubeSats teamed up on an impromptu optical, or laser, communications pointing experiment. The laser beam is seen as a brief flash of light close to the center of the focal plane, to the left of Earth's horizon.

'Quiet' light

Spectrally pure lasers lie at the heart of precision high-end scientific and commercial applications, thanks to their ability to produce near-perfect single-color light. A laser's capacity to do so is measured in terms of ...

Bursting the clouds for better communication

We live in an age of long-range information transmitted either by underground optical fibre or by radio satellites. But the throughput today is so great that radio frequency is no longer enough in itself. Research is turning ...
