Reconfigurable topological waveguide based on honeycomb lattice of dielectric cuboids
We show that the photonic crystal (PhC) made of dielectric cuboids with their centers forming a honeycomb lattice is characterized by a ℤ2${\mathbb{ℤ}}_{2}$ topological index when the longer sides of six cuboids point towards the center of hexagonal unit cell. While the C6v symmetry regar...
