Paper Abstract

We report first experimental evidences of spatial filtering of light beams in three-dimensional photonic crystals. The photonic crystals were fabricated in a glass bulk, where refractive index was modified by applying femtosecond laser pulses. We observe the modification of the angular spectra (the far field) in the central diffraction maximum of the transmitted radiation in accordance with the theory of spatial filtering.
