Abstract
A multi-band spectroscopic photodetector array including a substrate having a buried insulator layer in the substrate for electrically isolating a lower section of the substrate located below the insulator layer form an upper section of the substrate located above the insulator layer; and a plurality of photodetection elements each formed on a different portion of the upper layer and each including elements for detecting photons in a selected wavelength range; wherein each of the different portions of the upper section has a different thickness and wherein the thickness at least in part determines the selected wavelength of the photons detected by each of the detection elements.
