Abstract:
A photonic or phononic lattice structure, comprising:(a) a plurality of honeycomb layers stacked one above the other, with each honeycomb layer being formed by depositing and patterning layers of a first material and a second material to form a honeycomb structure from the first material with the remainder of the honeycomb layer comprising the second material, and with adjacent layers of the plurality of honeycomb layers being laterally displaced relative to each other along a diagonal thereof; (b) an interconnection layer sandwiched between each pair of adjacent honeycomb layers for interconnecting the adjacent honeycomb layers at vertices thereof, with the interconnection layer being formed by depositing and patterning layers of the first material to form dots wherein the vertices are interconnected, with the remainder of the interconnection layer comprising the second material, wherein the first and the second materials are selected from the group consisting of polycrystalline silicon, amorphous silicon, silicon nitride, silicon dioxide, silicate glasses, III-V semiconductors, II-VI semiconductors, II-IV semiconductors, transparent oxides, sol-gel glasses and spin-on glasses.
