<p>A periodic dielectric structure having a three-dimensional photonic bandgap and a method of fabricating same. The structure includes a plurality of stacked first and second two-dimensionally periodic slabs arranged in an alternating sequence. The first two-dimensionally periodic slabs comprise lower dielectric rods surrounded by higher dielectric material. The second two-dimensionally periodic slabs include higher dielectric rods surrounded by lower dielectric material. The rods of the first or second two-dimensionally periodic slabs are laterally offset from the rods of a nearest consecutive two-dimensionally periodic slab of the same type.</p> |
