| contents | We theoretically designed and experimentally demonstrated a mechanism to protect a spatially segregated mixed light-matter state, known as intercavity exciton-polariton in strongly coupled optical cavities. This excitation, shared across the coupled cavity array, exhibits remarkable robustness over a wide momentum range, without compromising photon-exciton mixing or the spatial separation of its photonic and excitonic components, which also enables a tunable heavy mass. Additionally, we unveil a direct connection between the transparency window, characteristic of slow-light experiments, and the protection of the intercavity polariton nature. Both phenomena originate from the strategic design of an energy-level landscape featuring a $Λ$-scheme, opening new avenues for exploring and utilizing these unique optical excitations in advanced photonic applications. |
