1. A wavelength selective photodetector comprising:

  • a substrate having a buried insulator layer 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

    photon detection means formed on said upper section of said substrate for detecting photons;

    wherein said upper section has a selected thickness and said selected thickness at least in part determines a wavelength range of said photons detected by said photon detection means.
