Here, we study the evolution of two-photon states in an elliptic array of waveguides.We characterize the photonic chip via coherent light tomography and use the results to predict distinct differences between temporally indistinguishable and distinguishable two-photon inputs, which we then compare with experimental observations. This work highlights the feasibility of emulation of coherent quantum phenomena in three-dimensional waveguide structures.English201110.1088/1367-2630/13/7/075003http://www.scopus.com/inward/record.url?scp=79960824692&partnerID=8YFLogxK
