(B) Calculated photonic band structure of an SF inverse opal along the high-symmetry directions in the first Brillouin zone. Frequency is in units of a/λ, where a is the lattice constant of the inverse opal and λ is the light wavelength in vacuum. Two partial photonic band gaps (red regions) exist along the L–U direction. Inset: illustration of the first Brillouin zone of the FCC lattice.
