Femtosecond time-evolution of the coherence properties of resonant secondary emission from excitons in GaAs quantum wells

Michael Woerner, Jagdeep Shah

Summary form only given. The femtosecond dynamics and the coherence properties of resonant secondary emission (RSE) from quantum wells is a subject of considerable current interest. We use a novel approach in which the sample is resonantly excited by a pair of phase-locked pulses, and the spontaneously emitted radiation is detected by femtosecond upconversion. This novel experimental technique allows us, for the first time, to investigate the temporal evolution and the coherence properties of RSE simultaneously.

Resonant Secondary Emission from Two-Dimensional Excitons: Femtosecond Time Evolution of the Coherence Properties

Michael Woerner, Jagdeep Shah

Using a novel technique, we simultaneously study the femtosecond dynamics of the amplitude and the coherence of resonant secondary emission from GaAs quantum wells. Two phase-locked pulses resonantly excite excitons in the semiconductor and the subsequently emitted radiation is detected by femtosecond up-conversion. In experiments at various delays and phases between the excitation pulses we identify three different contributions to the secondary emission with different coherence properties in time.
