Abstract
The authors report for the first time, normal incident infrared absorption around the wavelength of 13-15 μm from a 20 period InGaAs/GaAs quantum dot superlattice (QDS). The structure of a QDS has been confirmed by cross-section transmission electron microscopy (TEM) and by a photoluminescence spectrum (PL). This opens the way to high performance 8-14 μm quantum dot infrared detectors
