Abstract:The Hong–Ou–Mandel (HOM) interference of two light beams having different longitudinal spatial coherence properties is investigated theoretically and experimentally. The normalized second-order correlation function (

) is determined for the interfering photons from two sources of different angular widths using Feynman’s path integral theory. We find that the difference in angular width of the sources has an explicit impact on the HOM i… Show more
