Three views of a photonic crystal structure, fabricated from a hologram projected into photoresist.

Just as electrons in the periodic potential of a crystalline lattice have a modified energy spectrum, leading to forbidden ranges of energy in semiconductors wherein there are no electronic states, so a photon in a periodic array of dielectric material can also experience photonic bandgaps. This ability to sculpt the propagation of light and the scale of a single wavelength opens up many opportunities for designing novel optical devices.
