Abstract
Abstract Two dimensional photonic quasicrystals (PQCs) with different rotational symmetries are constructed based on holographic interference patterns. Their photonic bandgap (PBG) properties are obtained by using finite element method (FEM) to calculate the transmission and reflection spectra with different directions. The maximum gap-midgap ratio among different dielectric constant contrast and fill factor is given for all the PQCs to compare their abilities to produce bandgaps. The results show that 10-fold (five beams interference) and 12-fold quasicrystals are easier to form bandgaps than others. This may provide a reference to select appropriate quasicrystal structures for photonic devices and optimize device performance.
