Abstract

In this paper effect of parameters of introduced defect in photonic crystal on waveguiding properties are investigated. For this case 2-D photonic crystal structure is considered. Introduced defects are regular and irregular. These types of defects are studied and their effects on waveguiding properties are evaluated. It is shown that introducing defects cause the changes in the bandwidth and amplitude of the structure, and would lead to creation of new transmission bands in reflection band. For evaluation of the effect of introduced defects finite difference time domain (FDTD) method is used.
