Due to the rapidly increasing scale of PIC chips, high-density integration of waveguide arrays working with low crosstalk over broadband wavelength range is highly desired. However, the sub-wavelength regime of such structures has not been adequately explored in practice. Herein, we proposed a waveguide superlattice design leveraging the artificial gauge field (AGF) mechanism, corresponding to the quantum analog of field-induced n-photon resonances in semiconductor superlattices.
