Abstract :
In this presentation, we observed the coherent optical nonlinear interaction of exciton in a single InAs/GaAs self-assembled QD by using coherent control technique at the wavelength 1127 nm, 4.2 K. Due to the large diameter of InAs QDs in the longer wavelength range, dipole moment of confined excitons is predicted to be large so that coherent optical interaction such as Rabi oscillation is expected to be observed. Large dipole moment is one of the most important criteria to realize strong interaction between photons and excitons in QDs.
