Paper Abstract

A study is reported of the benefits of introducing antenna coupling to enhance the performance of IR detectors based on vanadium oxide. The spectral characteristics of devices containing arrays of inductively-coupled antennas have been measured and compared with the results of theoretical predictions. Response characteristics have been measured using focussed CO2 laser beams using an optical read-out technique. Performance enhancements of an order of magnitude can be achieved which can potentially overcome current limitations in achieving useful signal responses in detector elements with reduced absorber areas.
