Evidence for highly dispersive light propagation inside three‐dimensional photonic crystals is presented theoretically (see Figure and inside Cover) as well as experimentally. Polymer woodpile structures having a bandgap in the near‐infrared wavelength range have been fabricated by means of two‐photon polymerization, and the directions of the wavelength‐dependent light propagation inside the structures has been measured.
