Mems and metamaterial-based terahertz detector

Published

Journal Article

© 2012 TRF. We have designed, fabricated and characterized metamaterials-based far-infrared detector. The detector design, which combines metamaterials (MMs) and MEMS, is frequency selective. The enhanced absorption on the cantilever pixels from split-ring resonators (SRRs) leads to a mechanical deflection which is directly detected with a He-Ne beam. As a demonstration of our first-generation devices, we have fabricated and tested detectors at 95 GHz and 693 GHz with noise equivalent powers (NEP) of 10-8W/Hz1/2and single-pixel responsivity as high as 16,500 V/W in a room-temperature and pressure environment.
