We demonstrate two-dimensional gap solitons/soliton-trains by single-beam on-axis excitation in a self-defocusing ?backbone? photonic lattice. Interferograms and k-space spectra indicate staggered structure of the gap solitons arising from M-symmetry points of the first Bloch band.

A triphoton EPR-GHZ state, entangled in energy and momentum, is generated by using a hexagonally poled photonic crystal. The measured third order correlation function G3 (t1, t2, t3) has clear shown the entangled nature of the three-photon system.
