Abstract
Dielectric spheres synthesised for the fabrication of self-organized
photonic crystals such as opals offer large opportunities for the design of
novel nanophotonic devices. In this paper, we show a hexagonal superlattice
monolayer of dielectric spheres inscribed on a 3D colloidal photonic crystal
by e-beam lithography. The crystal is produced by a variation of the vertical
drawing deposition method assisted by an acoustic field. The structures were
chosen after simulations showed that a hexagonal super-lattice monolayer in
air exhibits an even photonic band gap below the light cone if the refractive
index of the spheres is higher than 1.93.
