A source emits a regular train of pulses separated in time by τ0.
(a) Design an experiment to measure the second-order autocorrelation of the source
and sketch the experimental setup.
(b) Discuss the requirement for the response time of the detector.
(c) What value of g(2)(0) would be obtained for the following cases: (i) each pulse
train containing exactly two photons and (ii) each pulse train containing exactly one
photon.
(d) Sketch the g(2) function for the cases described in (c).
