Abstract
Using a combination of interferometric-correlation and time-resolved intensity measurement techniques, we characterize the phase and amplitude of the coherent emission of semiconductor quantum wells resonantly excited by ultrashort optical pulses. We demonstrate that exciton-exciton interaction produces nonlinear phase shifts of the instantaneous frequency relative to the incident laser.
