Abstract
An apparatus is provided for nanoantenna-enhanced detection of infrared radiation. The apparatus includes one or more detector pixels. A plurality of detector pixels can constitute a focal plane array (FPA). Each detector pixel carries at least a first and a second subpattern of nanoantenna elements, with elements of the second subpattern interpolated between elements of the first subpattern. Each detector pixel also includes separate collection electrodes for collecting photogenerated current from the respective subpatterns.
