Abstract
An integrated photodetecting semiconductor optoelectronic component for measuring the intensity of each of the two colour constituents of dichromatic light irradiating the optoelectronic component includes a first SPAD and a second SPAD that detect photons over a broad range of wavelengths. The component also includes a semiconductor optical longpass filter that at least partially covers an active surface area of the first SPAD. The longpass filter is permissive to a first one of the two colour constituents of the dichromatic light and blocking the second one of the two colour constituents of the dichromatic light. The component further includes electronic circuitry for the readout and processing of detection signals delivered by the first and second SPAD. The electronic circuitry is adapted to provide a first intensity output signal and a second intensity output signal via a differential analysis based on the detection signals delivered by the first and second SPAD.
