This mode-order-dependent phase shift is achieved by a fractional Fourier transform realized by a time lens in one of interferometer's arms. We consider application of such a sorter with just two interferometers to sorting the Schmidt modes of a photon pair generated in spontaneous parametric downconversion and find the theoretical lower bond on the cross-talk probability of 5.5%.Lire moins >
