Displaced Fock states and photon correlations in Glauber-Fock photonic lattices

Here, we present the experimental analysis of light propagation in such Glauber Fock photonic lattices. The individual guides have been inscribed into fused silica employing femtosecond laser pulses and the desired coupling between the waveguides has been obtained by varying the inter-waveguide spacing accordingly. Figs. 1(a,c) show the calculated intensity evolution and experimental fluorescence images for an excitation of the first two guides, corresponding to a displacement of the Fock-states |0〉 and |1〉.
