We have designed and implemented from scratch an optical system to observe antibunching behavior in single photon sources (SPS). For this, we have incorporated a Hanbury-Brown and Twiss (HBT) setup to measure the second order autocorrelation function g(2). The HBT consists of a 50:50 beam splitter and two single-photon detectors.

HBT video.mp4The HBT interferometer is one of the most popular implementations to obtain the second order correlation function of a photon source in quantum experiments, due to its simplicity and efficacy to demonstrate single photon emission and characterize the properties of the source.
