Fig. 5: Stark shift of LP and UP versus pump intensity at cavity-exciton detuning δ = +5.1 meV.
From: Ultrafast dynamic stark shift of an exciton-polariton condensate
a Measured shift (squares and circles) below condensation threshold, at fixed average probe intensity of 13 mW cm−2. b Measured shift (squares) above condensation threshold, at fixed average probe intensity of 155 mW cm−2. The dashed lines represent the calculated Stark shift. The larger excitonic constituent of the LP, in comparison to the UP, yields a larger Stark shift. The Stark shift of the UP was detected below threshold only. Error bars represent standard deviation.
