我们演示了相干光学控制声子振荡使用飞秒控制脉冲。实验在InGaN/GaN多量子阱中进行。相干声子振荡是由一个紫外飞秒脉冲发起的。随后的操作,包括幅度和相位,相干声子振荡是通过控制脉冲的时间延迟和强度实现的另一个紫外飞秒脉冲。
We demonstrate coherent optical control of phonon oscillations using a femtosecond control pulse. The experiments were performed in InGaN/GaN multiple quantum wells. Coherent acoustic phonon oscillations was initiated with an UV femtosecond pulse. The subsequent manipulation, including magnitude and phase, of the coherent acoustic phonon oscillations was achieved using another UV femtosecond pulse by controlling the pulse time delay and intensity.
