Description

We study frequency-resolved femtosecond pump-probe reflectivity of a planar GaAs/AlAs microcavity. About 8 ps after a pump pulse, we observe an excess signal due to a non-adiabatic frequency change of the stored light by more than 4 linewidths away from the cavity resonance. Strikingly, the frequency change of light occurs at a time when the pump pulse is long gone. The frequency change is caused by the accumulated phase change of the light stored in the transient cavity. In agreement with an analytical model, the excess reflectivity is high when the cavity resonance frequency strongly shifts compared to the cavity linewidth within one cavity storage time.
