Abstract
Summary form only given. Progress in femtosecond lasers and ultrafast spectroscopy technology has enabled us to generate and directly observe the coherent oscillations of phonon modes. We demonstrate the coherent control of the initiated coherent acoustic phonon oscillation using a separate control UV pulse. The experiments were performed at room temperature on 14 periods InGaN-GaN MQWs.
