Bandgap properties of low index contrast aperiodically ordered photonic quasicrystals

TL;DR

This paper numerically investigates how the tiling design influences the bandgap properties of low index contrast photonic quasicrystals, highlighting the importance of spatial arrangement over symmetry.

Contribution

It demonstrates that tiling design, rather than symmetry, primarily determines the transmission properties of photonic quasicrystals with low index contrast.

Findings

Tiling design significantly affects bandgap properties.

Symmetry has less impact than spatial tiling.

Different tilings lead to distinct transmission behaviors.

Abstract

We numerically analyze, using Finite Difference Time Domain simulations, the bandgap properties of photonic quasicrystals with a low index contrast. We compared 8-, 10- and 12-fold symmetry aperiodically ordered lattices with different spatial tiling. Our results show that tiling design, more than symmetry, determines the transmission properties of these structures.
