Summary We report the modeling of woodpile and diamond structures for the use as photonic bandgap materials in which electromagnetic waves are forbidden in the bandgap, using an optical interference holographic set- up with a five- beam configuration consisting of four side beams and one central beam from the same half- space. By exploiting the advantage of the binarization of the interference pattern, using intensity cutoff, either the linearly or circularly polarized central beam can be used with linearly polarized side beams. More importantly, the beam configurations can be easily implemented experimentally as compared to other configurations in which the interfering beams are counter- propagating from both half- spaces.
