Fig. 7: Schematic of the possible experimental implementation proposal for achieving the proposed temporal multilayer structure and simulations based on WE method.

a A modulated ring resonator supports the synthetic frequency lattice model to realize the non-Abelian gauge field. b Scheme for measuring the non-Abelian AB interference using two such resonators. EOM electro-optic modulator, PS1(2) phase shifter 1(2), WM wavelength multiplexer, WDM wavelength demultiplexer, 50:50 50:50 coupler, PD photodetector. c, d Numerical calculation results based on WE method of the intensity contrast ρ between the two degenerate states after the interference versus initial intensity distribution α and phase difference β under the non-Abelian interference c without or d with GVD being included.
