Abstract

The Coulomb and carrier dynamics of the low-lying electronic states of 1.3 μm self-assembled quantum dots (QDs), at room temperature were reported. The dynamic absorption changes were probed at wavelengths across the first ecited state by time-resolved two-color differential transmission measurements following excitation in the ground state. Thus, wide tunability of the pump and probe wavelengths was achieved for the first time with low (kW) peak powers by a novel spectroscopic technique using the soliton self-frequency shift in a tapered microstructure fiber.
