Abstract: In this study, we report photonic band structures and optical transmissions of some SiC polytypes, such as 3C, 2H, 4H, and 6H, and their multilayers, which have the form of a hexagonal photonic crystal at two-dimensional (2D) scale. Through the finite-difference time-domain computational simulations, we found that spatial electric-field variations of electromagnetic waves depend on the radius of dielectric rods of the multilayer crystal structure, and the central structural geometry of 4H- and 6H-SiC hexagonal polytypes was found to cause a remarkable increase of the wave vector k in x and y directions. We also found a correlation between the local central structures of the optical modes in the 2D hexagonal crystal of 4H- and 6H-SiC polytypes. The wave-guiding in 4H- and 6H-SiC polytypes in the central core of the model geometry enabled the integration of defects to achieve a wide spectrum of technological functionalities, such as devices with striking features for miniaturized sensors and quantum information processing.
