Coherent Transient Optical Phenomena In Semiconductors

Duncan Steel, Jagdeep Shah

Coherent transient spectroscopy of resonances in gas phase atoms and molecules has provided considerable information on irreversible decay processes in these systems due, for example, to collisions. However, despite the presence of strong resonances in semiconductors such as excitons, the rapid dephasing times even at liquid helium temperatures made the study of coherent optical phenomena difficult.
