Analysis of splitters for self-collimated beams in planar photonic crystals. 2004

David Pustai, and Shouyuan Shi, and Caihua Chen, and Ahmed Sharkawy, and Dennis Prather

In this paper, we present methods for beam splitting in a planar photonic crystal, where the light is self-guided as dictated by the selfcollimation phenomenon. We present an analysis of a one-to-two and one-to-three beam splitter in a self-guiding photonic crystal lattice and validate our design and simulations with experimental results. Moreover, we present the first one-to-three splitter in a self-guiding planar photonic crystal. Additionally, we discuss the ability to tune the properties of these devices and present initial experimental results.
