Dynamic Stark Effect in Strongly Coupled Microcavity Exciton Polaritons
Dynamic Stark Effect in Strongly Coupled Microcavity Exciton Polaritons
We present experimental observations of a nonresonant dynamic Stark shift in strongly coupled microcavity quantum well exciton polaritons--a system which provides a rich variety of solid-state collective phenomena. The Stark effect is demonstrated in a GaAs/AlGaAs system at 10 K by femtosecond pump-probe measurements, with the blueshift approaching the meV …
