Abstract
In this study, the manipulation of engineered disorder effects in cylindrical photonic crystals is examined, with a focus on the influence of three varied types of disorder effects on the transmission spectra near the first five photonic band gaps of CPCs. The investigation employed the basic (ABA)N model, where A and B depict two isotropic dielectrics, and N is the number of periods. The impact of the disorder on the CPCs is analyzed and discussed in detail. In addition, the disorder-induced localization and delocalization of the electromagnetic waves are measured by the inverse participation rate and disorder-to-order energy ratio. These results are analyzed numerically. Based on this, the intrinsic connection between the defined parameters and the mechanism of disorder-influenced structure switching between the localized and transmitted states is investigated. All the above phenomena and findings might lead to a new understanding of electromagnetic wave transmission and localization in micro and nano-optical devices.
