The Investigation on Defect Mode Property of the Ten-Fold Photonic Quasicrystal

Abstract:

In this article,the transmission spectra of ten-fold photonic quasicrystals (PQC) are calculated by using finite-difference time-domain method (FDTD). By changing the crystal structure and introducing the point and line defects to devise the good micro-cavity and waveguide structures.In TE mode, the transmission spectra with defect modes are observed and quality (Q) factors are calculated to optimize the micro-cavity structure.It has the biggest Q factor when the central dielectric cylinder is removed. Furthermore, Design different waveguide structures and explore the field distribution. Different waveguide structure can control different light path and choose different incident light frequency.
