Abstract:

Information on propagating and evanescent Bloch modes as well as on remaining disorder is provided by experiments on titania woodpile photonic crystals with a complete three-dimensional photo­nic bandgap at visible wavelengths. Such frequency-resolved reciprocal-space mapping of visible spontaneous emission from 3D photonic crystals is analogous to angle-resolved photoemission spectroscopy (ARPES) on ordinary crystals.
