In this project, we use several photodiodes as Single Photon Avalanche Detectors (SPADs). We use a light bulb as the light source and grating to vary the wavelength of the light source. We will build a passive quenching configuration to get photons detected. Thus, by knowing which light source is working for the LEDs to detect photons, we can determine band gaps of each LEDs.
