TLDR
The carbon inverse opals provide examples of both dielectric and metallic optical photonic crystals that strongly diffract light and may provide a route toward photonic band-gap materials.Abstract:
Porous carbons that are three-dimensionally periodic on the scale of optical wavelengths were made by a synthesis route resembling the geological formation of natural opal. Porous silica opal crystals were sintered to form an intersphere interface through which the silica was removed after infiltration with carbon or a carbon precursor. The resulting porous carbons had different structures depending on synthesis conditions. Both diamond and glassy carbon inverse opals resulted from volume filling. Graphite inverse opals, comprising 40-angstrom-thick layers of graphite sheets tiled on spherical surfaces, were produced by surface templating. The carbon inverse opals provide examples of both dielectric and metallic optical photonic crystals. They strongly diffract light and may provide a route toward photonic band-gap materials.read more

TL;DR: In this paper, the authors describe photonic crystals as the analogy between electron waves in crystals and the light waves in artificial periodic dielectric structures, and the interest in periodic structures has been stimulated by the fast development of semiconductor technology that now allows the fabrication of artificial structures, whose period is comparable with the wavelength of light in the visible and infrared ranges.

Fabrication of photonic crystals for the visible spectrum by holographic lithography
M. Campbell,David N. Sharp,M. T. Harrison,M. T. Harrison,Robert G. Denning,Andrew J. Turberfield +5 more
TL;DR: This work describes a technique—three-dimensional holographic lithography—that is well suited to the production of three-dimensional structures with sub-micrometre periodicity, and has made microperiodic polymeric structures, and used these as templates to create complementary structures with higher refractive-index contrast.

TL;DR: In this article, the optical properties of submicrometre cylindrical cavities in metallic films were explored and it was shown that arrays of such holes display highly unusual zero-order transmission spectra at wavelengths larger than the array period, beyond which no diffraction occurs.
