ABSTRACT:
A light-sensing pixel is described that includes more than one detector element, each of which is sensitive to a range of wavelengths of the electromagnetic spectrums. The detectors are arranged in a readout circuit that can be constructed on a monolithic semiconductor product such that one or more of the detectors can be switched on or off to include or exclude an output contribution from said detectors and enhance the response of the pixel. Also, the detectors can included a laser-treated semiconductor sensor for efficient sensing of radiation in one or more regions of the spectrum. Arrays and imaging products using such pixels are disclosed.
