  Exploitation of time-frequency properties of SPDC photon pairs has recently
found application in many endeavors. Complete characterization and control over
the states in this degree of freedom is of paramount importance for the
development of optical quantum technologies. This is achieved by accessing
information both on the joint spectral amplitude and the joint spectral phase.
Here we propose a novel scheme based on the MICE algorithm, which aims at
reconstructing the joint spectral phase by adopting a multi-shear approach,
making the technique suitable for noisy environments. We report on simulations
for the phase reconstruction and propose an experiment using a Franson modified
interferometer.
