Abstract :
Summary form only given.We present data that combine the elegance and power of frequency and time-domain coherent spectroscopy with recent advances in QD probing that opens up a new direction of research for direct measurements of QD dynamics, coherent transients, and optical nonlinearities in these new nanostructures. The measurements are performed at T=6 K in a narrow 42-A single molecular beam epitaxy (MBE)-grown GaAs quantum well with 250 AlGaAs barriers.
