Optical millimetre-wave generation and signal processing have emerged as pivotal technologies in modern high-speed communications, advanced radar applications and imaging systems. These techniques ...

Earlier this year, researchers working on the Advanced Laser Interferometer Gravitational-wave Observatory (aLIGO) made the first ever detection of gravitational waves. The waves are believed to have ...

The Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo collaborations first detected gravitational waves in 2015. Ever since, they have continued to unveil new and exciting results ...

After the historic announcement in February 2016 hailing the discovery of gravitational waves, it didn’t take long for skeptics to emerge. The detection of these feeble undulations in the fabric of ...

Scientists have added another song to the soundtrack of the universe. On Wednesday (June 15), researchers with the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced that they had ...

Magnetic fields may play a bigger role in neutron star mergers than previously thought. A new study using advanced simulations shows that these fields can shift or suppress oscillation frequencies, ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

Four-wave mixing A weak optical signal (red) from a spacecraft transmitter can be amplified noise-free when it encounters two pump waves (blue and green) in a receiver on Earth. (Courtesy: Chalmers ...

Fungi processing audio signals. E. Coli storing images. DNA acting as logic circuits. It's possible, and in some cases, it's already happened. In any event, performing digital signal processing using ...

For the second time, scientists have glimpsed elusive ripples that vibrate the fabric of space. A new observation of gravitational waves, announced by scientists with the Advanced Laser Interferometer ...
