    "abstract": "We report the use of a (4+1)-beam optical interference holography technique\nto fabricate woodpile structures in photo-resists. The configuration consists\nof 4 linear polarized side beams arranged symmetrically around a circular\npolarized central beam with all the beams from the same half space, making it\neasily accessible experimentally. The fabricated woodpile structures are in\ngood agreement with model simulations. Furthermore, woodpiles with the diamond\nsymmetry are also obtained by exploiting the deformations of the photo-resists.\nDirectional bandgaps in the visible range are also observed for the samples\nwith and without the correct stacking of the woodpile structures.",
