Fig. 2

a The illustration of vertex-centered {6, 4} hyperbolic lattice in the Poincaré disk. Lattice sites in first, second and third layers are represented by red, blue and pink dots. Here, a half number of hexagons contain the staggered flux, as marked by triangles. b The schematic diagram of the designed vertex-centered hyperbolic photonic topological lattice with three layers. Detailed geometric parameters are presented. c, d Simulated transmission spectra by exciting the CPS and APS, respectively. e, f Simulation results of steady-state distributions of electric fields by exciting the CPS and APS with the wavelength being 1549.7 nm. g The steady-state distribution of electric fields by exciting the trivial bulk states at 1550.3 nm.
