Paper Abstract

A photovoltaic intersubband detector based on electron transfer on a cascade of quantum levels is presented: a Quantum Cascade Detector (QCD). Optical and electrical performances of a QCD are presented: high responsivity at null bias voltage about 44mA/W, high resistivity. Because they work with no dark current, QCDs are very promising for small pixel and large focal plane array applications. A dark current modelling is explained.
