Abstract
A photodetecting device for detecting different wavelengths includes a first photodetecting component including a substrate and a second photodetecting component including second absorption region. The substrate includes a first absorption region configured to absorb photons having a first peak wavelength and to generate first photo-carriers. The second absorption region is supported by the substrate and configured to absorb photons having a second peak wavelength and to generate second photo-carriers. The first absorption region and the second absorption region are overlapped along a vertical direction.
