Nano-Antenna IR Detectors ‘Ready For Industry Transfer’

Researchers at Sandia National Laboratories working to improve infrared sensors say that their gold nano-antenna technology is ready to be transferred out of the lab and into commercial development.

Working under project lead David Peters at Sandia’s National Security Photonics Center, the Albuquerque team claims that the new detectors improve sensitivity by a factor of three, while reducing dark current by as much as two orders of magnitude.

The higher performance results from the way that the minuscule antennas concentrate light onto a much thinner sensor layer than is typically found in infrared sensors. If successfully transferred into commercial use, it ought to result in cameras and sensors capable of delivering much clearer thermal images – with potential applications ranging from deep-sky astronomy to security.
