Effect of Metal Intercalating on Transmission Characteristics of One-Dimensional Photonic Crystal

Abstract:

To expand the bandgap's width of the one-dimensional photonic crystal, a crystal named SiO₂/Metal/MgF₂ is formed by joining some metals into the crystal SiO₂/MgF₂. Furthermore the Finite Difference Time Domain (FDTD) method is used to explore the metals' influence on the crystal's transmission characteristics. The simulation results show that the metals joined could expand the width of the one-dimensional photonic crystal's bandgap effectively and the bandgap's width increases when the metals' thickness increases. Meanwhile the bandgap's characteristic is affected by the metals' material-characteristic. The higher the plasma frequency is, the wider the bandgap's width will be and the more the number of the bandgaps will be. On the other hand, the metals' damping frequency has no significant effect on the bandgap, but would make the bandgap-edge's transmittance decrease slightly.
