    "abstract": "Optical interference holography has been proved to be a useful technique in\nfabricating periodic photonic crystals in which electromagnetic waves are\nforbidden in certain frequency bandgaps. Compared to periodic crystals\nquasicrystals, having higher point group symmetry, are more favourable in\nachieving complete bandgaps. In this report, we propose two seven-beam optical\ninterference configurations based on the reciprocal vector space\nrepresentations for quasicrystals to fabricate icosahedral quasicrystals.\nInterference simulations for the quasicrystals exhibit the full symmetry of an\nicosahedron. The result paves the path for the fabrication of photonic\nquasicrystals using holographic lithography.",
