In this paper, we demonstrate the near-field characterization of 3D PCs by using supercontinuum generation in a multi-mode fiber (MMF) as the bright BBS. A SNOM is utilized to directly observe the optical intensity distributions from 3D PCs, fabricated using the two-photon polymerization (2PP) technique, in the near-field regime.
