Abstract :
We propose a waveguiding mechanism based on the effective gauge potential for photons, where the core and cladding regions have the same dispersion relation but are subject to different gauge potentials. This can be realized in a dynamically modulated resonator lattice, and provides a dynamically reconfigurable mechanism for generating a one-way waveguide.
