In this study, we investigate the influence of strong cavity interactions on the protection of polartions against emitter inhomogeneities, hightlighting the role played by dark states in this system. Leveraging the cavity protection effect, we successfully engineer the spectrum of polaritons, resulting in the generation of polartions with muliple frequencies. This can lead to applications in quantum networks, particularly for shaping single-photon emission.
