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