Paper Abstract

The structuring of high quality complex optical materials yields remarkable flexibility in the fabrication of nanostructures. These artificial materials can be used to manipulate light. The photonic band structure of a honey comb lattice composed of hollow shell rod with GaAs wall has been investigated by using standard Eigen mode expansion (EME) techniques. The dispersion characteristics of the dielectric material determine the tunability of the band gap as well as appearance of surface plasmon polariton (SPP) mode. Dispersion less flat band was observed for the frequency region where dielectric constant changes its sign. We demonstrate band gap tuning by applying external perturbation such as temperature change or varying external magnetic field. Using our band solver we extend the existing methodology by adjusting the dimension of the lattice to observe the desired effects. In addition to that our method studies the lacking of structural integrity due to presence of absorption.
