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.

A multi-band spectroscopic photodetector array comprising:
- a substrate having a buffed insulator layer in said substrate for electrically isolating a lower section of said substrate located below said insulator layer from an upper section of said substrate located above said insulator layer;
- and
- a plurality of photodetection elements each formed on a different portion of said upper section and each including means for detecting photons in a selected wavelength range;
- wherein said different portions of said upper section have different thicknesses and wherein said thicknesses at least in part determine said selected wavelength range of said photons detected by each of said detection elements.
