The Fibonacci band edge states were found to exhibit mode beating, a sizable field enhancement, and a group velocity reduction that was 3 times larger than that observed in three-dimensional colloidal photonic crystals of polystyrene. However, as in the photonic crystal case the Fibonacci band edge states exhibit band edge resonances which were critically localized due to the Fibonacci disorder. Fibonacci systems can provide an interesting alternative to regular photonic crystals for the realization of photonic devices, such as optical filters with a self-similar spectrum and a high wavelength selectivity in the band edge region.
