Ashley N. Rice, [email protected] Nanoantennas with “slots” that correspond to mid-IR wavelengths are a new way to tune IR light into mechanical action – which could lead to more sensitive IR cameras and more compact chemical-analysis techniques. Existing IR detectors use cryogenically cooled semiconductors or microbolometers to correlate changes in electrical resistance to temperatures. Both techniques require expensive, bulky equipment to be sensitive enough for spectroscopy applications. The optomechanical thermal IR detector developed at the University of Pennsylvania, however, works by...Read full articleRelated content from Photonics MediaARTICLESSilicon CCD Camera Peers into Mid-InfraredResearchers at the University of California, Irvine used the nonlinear optical properties of the silicon (Si) chip in a Si-based camera to enable a mid-infrared (MIR)-specific response in the camera....Photonics Spectra October 2020 IssueDBR Suppresses Spectral Crosstalk for Improved IR Imaging PerformanceNorthwestern University engineers found a way to suppress spectral crosstalk between dual-band long-wavelength photodetectors.
