When connected to a laser beam, the new thin-film circuit produces finely tailorable terahertz-frequency waves. The device opens up a world of potential applications in optics, imaging and telecommunications. (Image: EPFL)

Chips using integrated photonic circuits could help close the 'terahertz gap'

The chips show promise for a whole host of applications in optics, spectroscopy, imaging and telecommunications

InGaAs and event-based sensors still rely on silicon CMOS readout ICs

Sense of purpose

Greg Blackman explores the work being done on InGaAs sensors, along with other types of novel sensor that could find their way into the machine vision market
