We demonstrate ultrafast control of a strongly coupled light-matter system via a giant ac Stark effect in a specially designed strongly coupled microcavity using ultrafast pump-probe spectroscopy. We observe polariton energy shifts larger than the Rabi energy, enabling the implementation of strong noninvasive potentials for robust and ultrafast polaritonic switches. A nonperturbative treatment has been utilized to correctly describe the underlying physics of the giant Stark shifts in our strongly coupled light-matter system and corresponds well to the experimental results. Our findings shed new light on nonperturbative interactions and pave the way for all-optical quantum technologies.
