Electrical engineers at Duke University report they have built a record-setting pyroelectric photodetector that uses trapped light in a plasmonic nanogap to capture a signal in just 125 picoseconds ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the ...
