Morphology, band structure, and optical properties of artificial opals
Contributors
Description
Bulk polystyrene opals have been grown. Variable incidence angle reflectance spectroscopy is used to probe their
photonic band structures. Several different structures are observed and accounted for by theoretical calculations of
photonic bands and density of states. The results yield a clear distinction between diffraction in the direction of
propagation by the (111) family planes (leading to the formation of the stop band) and diffraction in other directions by higher-order planes (corresponding to excitation of photonic modes in the crystal).
