Abstract:
In this study, three-component One-Dimensional (1D) Photonic Crystal (PC) structures were investigated by modeling
them as two-component PCs with an additional regular layer. The Gap Map approach and the Transfer Matrix Method
were used in order to mathematically describe these structures. The introduction of a third component to a 1D PC allows
manipulation of the optical contrast to a high degree of precision by varying the thickness and refractive index of the
additional layer. It also partially reduces the area of the photonic band gaps (PBGs) on the gap map, leaving the
remainder of the PBG area unchanged from that of the gap map for the original, two-component, PC. Using this
approach to decrease the optical contrast in photonic crystals allows omni-directional bands to be obtained in highcontrast
periodic structures constructed from, for example, an array of silicon and air.
