Photonic Quasicrystals (PhQCs) possessing quasiperiodic spatial tiling and rotational symmetries not achievable by photonic crystals have permitted to realize photonic band-gap (PBG) structures at low dielectric contrast. We compared 8-, 10- and 12-fold symmetric quasi-crystalline lattices with different spatial tiling for each symmetry. Our computations of transmittance spectra for low dielectric contrast, based on FDTD method, prove that tiling design more than symmetry determines the PBG properties of the structure.

Abstract

Photonic Quasicrystals (PhQCs) possessing quasiperiodic spatial tiling and rotational symmetries not achievable by photonic crystals have permitted to realize photonic band-gap (PBG) structures at low dielectric contrast. We compared 8-, 10- and 12-fold symmetric quasi-crystalline lattices with different spatial tiling for each symmetry. Our computations of transmittance spectra for low dielectric contrast, based on FDTD method, prove that tiling design more than symmetry determines the PBG properties of the structure.
