Abstract
This paper presents a photonic bandgap simulation for real holographic 3D photonic crystals instead of optimal photonic crystal structures. The holographic photonic crystals are formed through five-beam interference generated by multi-layer phase mask. The photonic bandgap depends on the relative phase difference among the interfering beams. A maximum bandgap of 20% of the middle bandgap can exist in these structures which can be formed through single beam, single phase mask, and single laser exposure process. We also fabricate the multi-layer phase mask by placing a spacer layer between gratings. Using the multi-layer phase mask, photonic crystal templates are holographically fabricated in a photosensitive polymer.
