Here, we report an attractive platform of low-thermal-mass resonators inspired by the architectures of iridescent Morpho butterfly scales. In these resonators, the optical cavity is modulated by its thermal expansion and refractive index change, resulting in {\textquoteleft}wavelength conversion{\textquoteright} of mid-wave infrared (3-8 {\textmu}m) radiation into visible iridescence changes. By doping Morpho butterfly scales with single-walled carbon nanotubes, we achieved mid-wave infrared detection with 18-62 mK noise-equivalent temperature difference and 35-40 Hz heat-sink-free response speed. The nanoscale pitch and the extremely small thermal mass of individual {\textquoteleft}pixels{\textquoteright} promise significant improvements over existing detectors. Computational analysis explains the origin of this thermal response and guides future conceptually new bio-inspired thermal imaging sensor designs.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=785), last updated on Mon, 07 May 2012 21:14:47 -0500" }
