    "abstract": "We report the use of an optical interference holographic setup with a\nfive-beam configuration, consisting of four side beams and one central beam\nfrom the same half space, to fabricate woodpile and diamond structures for the\nuse as photonic bandgap materials in which electromagnetic waves are forbidden\nin the bandgap. By exploiting the advantage of the binarization of the\ninterference pattern, using intensity cut-off, either linear or circular\ncentral beam can be used. More importantly, the beam configurations can be\neasily implemented experimentally as compared to other configurations in which\nthe interfering beams are counter-propagating from both half spaces.",
