Abstract
Wavelength recognition is one of the important functions of photodetectors. However, wavelength recognition of the reported photodetectors generally depends on light intensity, which limits the practical applications. Here, a light intensity-independent wavelength recognition scheme based on vertically stacked transparent photodetectors is reported. By analyzing light intensity attenuation behavior in the multiple stacked photodetectors, the wavelength ofincident light can be accurately determined. Due to the high transparency of the detectors, the multiple stacked detectors allow incident light to pass through. Meanwhile, since the attenuation coefficients at different wavelengths are attributed to the detector's absorption characteristics, the intensity of incident light and its wavelength can be determined by analyzing the attenuation coefficients measured through each stacked detector. Consistent wavelength values obtained at different light intensities verify the light intensity-independence of the multistacked detector system.
