Abstract
Large absolute band gaps are searched among photonic crystals whose unit cells are formed by large dielectric pixels. To speed up the computation, a fast plane-wave expansion method is introduced for calculating the band structures for such special photonic crystals. Two structures are found to have absolute band gaps of 0.1158(2πc/a) and 0.11(2πc/a) (a is the period of the square lattice) at the low- and high-frequency regions, respectively. Both structures are stable and convenient for fabrication.
