Paper Abstract

A hyper-spectral quantum dot infrared photodetector (QDIP) based on doublecavity comb filter is reported. The hyperspectral QDIP uses a double cavity comber filter and a novel transparent conductive carbon nanotube (CNT) thin-film network as the electrode. By tuning the bias of the transparent electrode coated on the membrane, the cavity length and corresponding passband of the filter can be changed accordingly with low optical loss. Such MEMS-based hyper-spectral QDIP would also enable quick spectral scan of IR characteristics of chemical and biological materials.
