Abstract

This oral presentation discusses plasmonic vanadium dioxide microbolometers with wavelength and polarization sensitivity. Improved accessibility to high performance infrared technology is a necessity in fields as diverse as firefighting and spectroscopy; in many cases the cost to benefit ratio is too high. The current low-cost infrared detector market is dominated by vanadium dioxide microbolometers which suffer from lower performance than photodetectors and display poor spectral selectivity. Incorporating plasmonic nanostructures into vanadium dioxide based thermally-engineered arrays can enable high performance wavelength and polarisation sensitive detection without the need for filters and cooling. A variety of designs including plasmon-enhanced bolometers and multilayer suspended membranes are presented.
