Single photons are vital to quantum computing, information processing, and transportation. Popular single-photon experiments are one or two-photon interference, classification of the light source, and characterization of detectors. Currently, the most efficient detector in the telecom wavelength is the Superconducting Nanowire detector. How- ever, experiments have been successful in demonstrating single-photon measurements can be done with unconventional detectors. One such method employed an EMCCD camera to observe spatial correlations between pixels with single photons. This thesis aims to test non-single photon-counting PIN photodetectors to observe time-correlation measurement. The improved detection model uses a high-resolution 2GHz oscilloscope and a cross-correlation algorithm. Results were compared with coincidence measurements using an SNSPD and TAC module. Previous PIN-related single- photon experiments mainly used PIN avalanche detectors. We aim to accomplish the same task with Thorlabs PDA-CF 10 amplified detectors.
