摘要

Moiré patterns have become a powerful platform for exploring emergent phenomena in both electronic and photonic systems. However, most studies to date have focused on periodic systems where a small twist or lattice mismatch generates a superlattice or a quasi-periodic order. Here we show that rich moiré states can also arise in non-periodic photonic structures in the absence of global translational or rotational symmetry. We present a reconfigurable platform of two concentric ring-patterned slabs and dynamically probe the optical response as a function of relative displacement. We reveal two distinct emergent regimes: the hypermoiré state, where interlayer coupling is distributed among multiple spatial channels to form a dense array of curved bands, and the moiré singlet, where interlayer coupling is funneled into a highly localized mode spanning the device. Our findings establish a route to tunable optical states in non-periodic bilayers and extend moiré photonics beyond periodic superlattices.
