Abstract :
We propose and show experimentally uniform axisymmetric spatial filtering of light beams by three-dimensional axisymmetric photonic microstructures. Such gapless structures (similar to photonic crystals) were recorded in bulk of glass. Angular filtering of 25 mrad is demonstrated experimentally.
