<p>A monolithic optical detector (10) for determining spectral content of an incident light (18) includes at least a first and second well in a substrate (16), the second well (14) formed proximate the first well (12). 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 (46), 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.</p> |
