Abstract
The University of Central Florida invention is a novel optical antenna array that allows efficient broadband light coupling across the long wave infrared (LWIR) band (or MWIR, SWIR) to the underlying VO2 phase-change material which triggers electronic oscillation. Tracking the change in the oscillator frequency modulation (FM) with respect to incident IR radiation while the VO2 system is electrically biased in the high-temperature coefficient of resistance (TCR) semiconductor (S)-metal (M) transition (SMT) edge, offers significantly higher noise performance compared to the conventional amplitude modulation (AM) based IR detection. Overall, the frequency modulated high-sensitive infrared detection scheme will add an unexplored dimension to room temperature infrared detection and imaging techniques. The proposed frequency modulation (?f) (FM) based IR detection scheme offers noise resistance and higher photon detection sensitivity (?f/PIR).
