Wavelength selective photodetector

摘要

A wavelength selective photodetector including: a substrate having a buried insulator layer for electrically isolating a lower section of the substrate located below the insulator layer from an upper section of the substrate located above the insulator layer; and a photon detector formed on the upper section of the substrate for detecting photons in a selected wavelength range, wherein the upper section has a selected thickness and the thickness determines at least in part the selected wavelength range of the detected photons.
