Optical Properties of One- and Two-Dimensional Periodic Photonic Structures
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 10
Abstract
This paper presents a theoretical exploration of the electrodynamic behaviours of one- and two-dimensional photonic crystals, consisting of composite material and dielectric layers. Specifically, we determine the photonic-bandgap for various photonic materials, such as Gallium Arsenide (GaAs), Sapphire (Al2O3), and Plexiglas (C5O2H8)n. It is shown that the width of the photonic-bandgap depends primarily on the physical parameters of the structure. In addition, the higher the permittivity of the material, the greater the number of bands of significant width. Using the method of decomposition of plane waves, we show that GaAs is the material having a larger prohibited bandwidth. Finally, we compare numerical results in 1-D and 2-D system.
