Photonic bandgaps and resonators in the one-stage Sierpinski gasket basis

摘要

This paper discusses theoretical calculations of photonic bandgaps found in the one-stage Sierpinski gasket basis in the hexagonal lattice. Dielectric triangles and cylinders as well as air triangles and cylinders are investigated. All of these structures exhibited complete bandgaps, with the largest complete gap having 6.1% fractional width. The largest TE and TM polarization gaps were 23% and 40% fractional width, respectively. Resonators constructed from these crystals with a Q ten to 2000 times greater than resonators constructed using one cylinder in the hex lattice are demonstrated.
