Resum

Silicon Photomultipliers (SiPMs) are emerging as promising photon detectors in quantum optics due to their high photon detection efficiency(PDE), excellent timing resolution, and photon-number resolution capabilities. Their potential to replace conventional single-photon detectors makes them attractive for applications in many quantum technologies. In this study, I first performed a detailed characterization of SiPMs to assess their performance parameters, including dark count rate(DCR) and singlephoton time resolution(SPTR). I then implemented these SiPMs in an existing experimental setup designed to evaluate single-photon sources (SPS), in order to test their feasibility for use in quantum-optical experiments. Although challenges arose, including alignment limitations and high dark count rates inherent to SiPMs, the system was able to register photon count rate changes under various SPS conditions. While anti-bunching was not observed, the results provide practical insights into the integration of SiPMs in singlephoton-level experiments and outline conditions necessary for future successful implementation.
