Abstract: A photodetecting device is provided. The photodetecting device includes a first photodetecting component including a substrate having a first absorption region configured to absorb photons having a first peak wavelength and to generate first photo-carriers, and a second photodetecting component including a second absorption region configured to absorb photons having a second peak wavelength different from the first peak wavelength and to generate second photo-carriers. The first photodetecting component further includes two first readout circuits and two first control circuits for the first photo-carriers and electrically coupled to the first absorption region. The second photodetecting component further includes two second readout circuits and two second control circuits for the second photo-carriers and electrically coupled to the second absorption region, wherein the two second readout circuits are separated from the two first readout circuits, and the two second control circuits are separated from the two first control circuit.
