Abstract:
Photonic topology manifests itself even above room temperature and thus is important for study of topology physics and future applications. We design a photonic crystal with Z2 topology purely based on dielectric material, such as silicon, by deforming honeycomb lattice of dielectric cylinders. The key point is to identify in the Maxwell system an emergent time-reversal symmetry similar to that of electronic systems without any gyromagnetic, bi-anisotropic or piezo-magnetic material. The topological photonic crystal can be fabricated easily by means of the well-established nanotechnology. Our work is expected to stimulate further activities in fields of topological physics and related materials science.
