These systems are employed in the design of the holey fiber.
A '90s/'00s book about these systems authored by Joannopoulos, Johnson, Winn, and Meade has a mind-boggling 10,000 citations. Fabricating one variety of these systems is done by the self-assembly 3 of microscopic spheres in a colloid as the colloid is evaporated, forming a synthetic opal whose inter- stitial space is then filled by a dielectric before dissolving the spheres. These systems are employed in the design of the holey fiber. Fabricating another variety of these systems involves stacking dielectric6 "logs" in alternating orthogonal directions to form a "woodpile". The hole slab and rod slab exam- ple of these systems differ from each other in that the former has TE-like modes while the latter has TM-like modes. The first example of these systems to be fabricated was a dielectric that had been9 mechanically drilled along the three lattice vectors of an fcc lattice and was named Yablonovite after its discoverer. Their simplest example consists of (*) alternating layers with different dielectric constants, forming a Bragg mirror. For a specific range of optical frequencies, the local density of states of these systems12 is zero at their namesake "band gap". For 10 points, name these optical analogs of conductive lattices.
