The MPPC (multi-pixel photon counter) is one of the devices called silicon photomultipliers (SiPM). It is a photon-counting device using multiple APD (avalanche photodiode) pixels operating in Geiger mode. Although the MPPC is essentially an opto-semiconductor device, it has excellent photon-counting capability and can be used in various applications for detecting extremely weak light at the photon counting level.
