    "abstract": "We present a novel, real-time, experimental technique for linear and\nnonlinear Brillouin zone spectroscopy of photonic lattices. The method relies\non excitation with random-phase waves and far-field visualization of the\nspatial spectrum of the light exiting the lattice. Our technique facilitates\nmapping the borders of the extended Brillouin zones and the areas of normal and\nanomalous dispersion within each zone. For photonic lattices with defects\n(e.g., photonic crystal fibers), our technique enables far-field visualization\nof the defect mode overlaid on the extended Brillouin zone structure of the\nlattice. The technique is general and can be used for photonic crystal fibers\nas well as for periodic structures in areas beyond optics.",
