Özet

In this paper, the transmittance of transverse electric field (TE) in one-dimensional photonic crystals (1D PC’s) with different defect layer geometries is theoretically investigated in visible region by using finite-difference time-domain (FDTD) method. TiO2is used as higher refractive index material, SiO2is used as lower refractive index material and Al2O3is used as defect layer material. Our results show that defect layer geometry effect TE transmittance peak value and position therefore we achieved the optimum geometry for the highest transmittance. We also find that if we take the defect layer materialAl2O3, thickness 80 nm and position as (AB)4C(AB)4, highest transmittance peak value occurred.
