A new ultrathin photodetector captures light across the full spectrum in just 125 picoseconds, opening the door to faster, smarter imaging technologies.

Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date that works by absorbing heat generated by incoming light.
