Abstract

Photonic crystals (PCs) are artificial wavelength-scale periodic structures that enable the manipulation of light propagation and possess intriguing dispersive characteristics such as super-prism, negative refraction, and slow/fast light [1]. Besides all these properties, self-collimation phenomenon is another anomalous dispersive property of PCs that provides the existence of non-diffracting Bloch modes within the PCs [2]. The possibility of beam propagation/guiding inside PC media without spatial broadening is essential for optical components in integrated circuits such as optical interconnects, routers and power splitters [3].
