Abstract: We show that inter-band photonic transition, as induced by dynamic modulation, can be used to achieve linear optical isolators that completely reproduce the functionality of magneto-optical devices. We further show that the phase of the modulation induces an effective gauge transformation for photon wavefunctions. By controlling the phase distribution, one can then achieve an effective magnetic field for photons. As an evidence of such effective magnetic field, we show an effective Lorentz force for photons, as well as a dynamically-induced one-way edge mode in dynamically modulated photonic resonator lattice.
