We introduce a practical, new, face-centered-cubic dielectric structure which simultaneously solves two of the outstanding problems in photonic band structure. In this new "photonic crystal" the atoms are nonspherical, lifting the degeneracy at the 8 point of the Brillouin zone, and permitting a full photonic band gap rather than a pseudogap. Furthermore, this fully three-dimensional fcc structure lends itself readily to microfabrication on the scale of optical wavelengths. It is created by simply drilling three sets of holes 35.26 oA' vertical into the top surface of a solid slab or wafer, as can be done, for ex
