Fabrication of 2D and 3D photonic quasi-crystals with high rotation symmetry by holographic lithography technique

We demonstrate using a double-exposure three-beam and/or three-beam-plus-one interference technique, one can easily and efficiently fabricate 2D and/or 3D quasi-periodic structures. Using the multi-surface prism, our fabrication technique becomes a compact and robust way to produce different kinds of structures, periodic or quasi-periodic.
