TWIPS -- sonar inspired by dolphins

Scientists at the University of Southampton have developed a new kind of underwater sonar device that can detect objects through bubble clouds that would effectively blind standard sonar.

New device for ultrafast optical communications

A new device invented by engineers at UC Davis could make it much faster to convert pulses of light into electronic signals and back again. The technology could be applied to ultrafast, high-capacity communications, imaging ...

Compressing photonic signals for greater bandwidth

Cornell researchers have developed an ingenious method to time-compress optical signals. The process could enable optical communication systems to carry many more bits per second or could also be used to generate short bursts ...

New method reveals all you need to know about 'waveforms'

The National Institute of Standards and Technology has unveiled a method for calibrating entire waveforms -- graphical shapes showing how electrical signals vary over time -- rather than just parts of waveforms as is current ...
