ABSTRACT:
A method of forming a periodic index of refraction pattern in a superlattice of a solid material to achieve photonic bandgap effects at desired optical wavelengths is disclosed. A plurality of space group symmetries, including a plurality of empty-spaced buried patterns, are formed by drilling holes in the solid material and annealing the solid material to form empty-spaced patterns of various geometries. The empty-spaced patterns may have various sizes and may be formed at different periodicities, so that various photonic band structures can be produced for wavelength regions of interest.
