Figure 1 | Configuration of the 1D synthetic SSH model.

Caption

(a), an illustration of two identical coupled ring resonators with coupling strength κ, while ring A undergoes dynamic modulation, which can be mapped into a 1D photonic SSH model along the frequency dimension with lattice sites of two super modes. (b), The analytical band structures of the synthetic SSH model under different hopping strengths. Inserted: the corresponding geometric phases as the wave vector evolving through the first Brillouin zone.
