Author Affiliations +
One of the most surprising things about photonic crystals is not the existence of the band gap, but the fact that a large, ordered array of scatters can be transparent to light within certain spectral regions. We have identified a new, general effect in which the band gap of a photonic lattice can be suppressed by unexpected mode degeneracy, rendering a photonic crystal completely transparent to all frequencies across two or more distinct bands.
