Realization of Woodpile Structure Using Optical Interference Holography

Optics 2009-11-13 v1

Abstract

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.
