The disclosed subject matter provides systems and methods for spatial and spectral modulation of light. An example system for modulating light can include a substrate and a plurality of meta units, coupled to the substrate and configured to spatially and spectrally modulate the light, wherein the plurality of meta units includes a perturbation and forms a perturbed lattice supporting a quasi-bound state in the continuum.
