Abstract

Strong light-matter interaction in semiconductor microcavities manifested in new dressed eigenstates - exciton-polaritons, has been of great interest in the last decade, resulting in various exciting and intricate phenomena including high-temperature Bose-Einstein condensation and superfluid behaviour [1-3]. A novel approach to provide dynamic energy shifts for exciton-polaritons was recently demonstrated based on the AC Stark effect [4], enabling ultrafast switching [5], phase imprinting and modulating potential landscapes faster than the condensate coherence time. However, the magnitude of the fast AC-Stark-based modulation in standard microcavities is limited to the weak perturbative regime.
