We calculate output coincidence rates for a biphoton state propagating through a Mach-Zehnder interferometer, with delay stages present both before and within the device. A time-dependent relative phase between interferometer paths, supplied by the presence of two acousto-optical modulators, gives rise to a time-dependent coincidence rate containing multiple oscillation frequencies. We show that frequency decomposition of the coincidence signal allows for the extraction of amplitude and relative phase information concerning the symmetric and antisymmetric components of the joint spectral amplitude of the biphoton input source.
