Metamaterial infrared detectors (Conference Presentation)
Author(s): Sanjay Krishna

Paper Abstract

There is an increasing demand for high performance long wave infrared (LWIR) detectors with multispectral capability. Meta-materials and antenna based concepts offer some interesting solutions to win the signal to noise ratio and provide enhanced functionality at the pixel level. The long wave infrared region is appealing due to the low metallic loss, large penetration depth of the localized field and the larger feature sizes compared to the visible region. I will discuss approaches to realize multispectral detectors with examples of double metal meta-material design combined with Type II superlattice absorbers (collaboration with Padilla group at Duke University).
