Abstract

We review the status of 3D anisotropic crystals based on opal-semiconductor and opal-polymer nanocomposites with respect to controlling the spontaneous emission in space and frequency. An approach to grow photonic crystal structures form PMMA balls containing a laser dye is also presented. We show that depending mainly on the refractive index contrast and the choice of light emitter, photonic crystal effects manifest themselves in several forms. These are illustrated by choosing a suitable dopant for the polymer, such as laser dyes or rare-earth ions, under condition that their fluorescence should fall within the stop-band of the photonic crystals. The refractive index contrasts obtained are far from ideal and yet the impact of the anisotropic PBG is manifested unambiguously in, for example, the change of the density of states of photons and the directionality of the emission.
