  • METHOD AND APPARATUS FOR OPTICAL DETECTOR WITH SPECTRAL DISCRIMINATION
    Publication number: 20030132369
    Abstract: A monolithic optical detector for determining spectral content of an incident light includes at least a first and second well in a substrate, the second well formed proximate the first well. The first well is configured to be exposed to incident light and for generating a first photocurrent as a function of the incident light. The second well is configured to be shielded from the incident light and for generating a second photocurrent as a function of the incident light. Lastly, a processing and control unit, responsive to the first and second photocurrents, determines an indication of spectral content of the incident light. A method and device parameter controller are also disclosed.
