Ultrafast Time-Resolved Spectroscopy of Quantum Confined Semiconductor Heterostructures,two topics: the femtosecond time resolved investigations of the nonlinear optical response of semiconductor quantum wells in strong perpendicular magnetic field, and the investigations of many-body effects in the temporal lineshape of coherent emission from semiconductor quantum wells.

Coherent Optical Phenomena of Quantum Well Excitons in a Magnetic Field,citon Zeeman levels and a rotation of the photon echo polarization are observed and analyzed. We show that exciton spin orientation is maintained for several tens of picoseconds. Fast oscillations of the differential absorption and the four wave mixing signal are observed and attributed to bi-excitonic nonlinearity.
