Summary: Noise logic is introduced based on the wavelength dependent photocurrent noise of an InGaN/SiNx/Si uniband diode photodetector. A discrimination map is created to distinguish different wavelengths based on the larger photocurrent noise for red light compared to green light. By utilizing the standard deviation of photocurrent noise, a minimum measurement time of four seconds is determined for safe wavelength distinction. A logic NOT gate is implemented using red or green light as binary inputs and the photocurrent noise above or below a defined threshold as binary outputs.

Summary: A novel self-powered InGaN/SiNx/Si uniband diode photodetector is introduced in this study. The performance of the photodetector, including photocurrent, responsivity, and bandwidth, is investigated in different operation modes under illumination of light with different wavelengths. The presence or absence of energy barriers for electron and hole transport in the photodetector operation leads to different noise levels, which is crucial in dual-wavelength photodetection.
