N2 - Topological photonic systems have been explored extensively due to the robust electromagnetic states they support. In this work, we propose a finite-difference supercell approach to analyze the topological property of photonic crystal (PC) structures. Meanwhile, the pseudospin polarized edge states at the interface of two PC structures with different topologies are studied. The direction of the energy flow is found to be determined by the helicity of the pseudospin polarization.
