Abstract
Photonic crystals (PhC) are very interesting periodic material entities with many attractive physical properties. Moreover opaline-based PhC represent very simple way of realization of these PhC. In this contribution, we present our recent studies on both modeling and realization of these opaline based PhC (primarily based on SiO2). Presented opals were prepared by self-assembly method based on the modification of a simple sedimentation technique. This alternation represented the spatial restriction of space region where the opal was constructed. Even more interesting properties, including the presence of the band gap, can be revealed via infiltrated and / or inverse opals. We have chosen photoconductive poly(9-vinylcarbazole) (PVK) as the material for infiltration and final inversion procedure. We have produced highly regular opals and stable inverse opals. Numerical modeling of these opaline structures has been carried out with the use of both MPB (simulations of simple and infiltrated PhC) and Meep tools (simulations of PhC in inverse configuration with the dispersion of PVK taken in account).
