摘要：Multi-dimensional optical gratings () of a background material () having a firstrefractive index and cells () of at least one different refractive index. The cells () mayoccupy two-dimensional or three-dimensional grids, defining the optical gratings asplanar gratings () or cubical gratings (), and thus providing two or three sets of surface-

to-surface separations, or thicknesses, and cell-to-cell separations. The respective sets ofsurface-to-surface separations and cell-to-cell separations used may particularly beselected according to Bragg's law to selectively scatter respective light wavelengths.
