- 11:25, 22 February 2024 Abassyahbana talk contribs created page Photodiodes as Single Photon Detectors (Created page with "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.")

Alternatively, if a stable laser is available, the PDH technique can be used to stabilize and/or measure the instabilities in an optical cavity length. In this pr...")
