| Research Abstract |
We have investigated coherent phonons and Rabi oscillations resulting from quantum interference between two polariton states in semiconductor microcavities by using THz-domain modulation spectroscopy and pump-probe method, to clarify the dynamics of coherent wave packets generated in semiconductor nano-structure films. We demonstrate that short-lived Rabi oscillations and long-lived coherent phonons are coupled to each other through the polarization interaction between the excitonic components of polaritons and coherent phonon, and the coherent phonons are extremely enhanced by Rabi oscillations.
