An optically driven metamaterial with a photoswitchable weak and strong molecular‐plasmonic coupling is demonstrated. In this active perfect absorber, the absorption band can be broadened more than 150 nm (split with an energy difference of 780 meV) by UV irradiation, which demonstrates a new class of optically tunable metamaterial absorber for visible frequencies.
