Abstract

We report the experimental observation and control of space and time-resolved light-matter Rabi oscillations in a microcavity. Our setup precision and the system coherence are so high that coherent control can be implemented with amplification or switching off of the oscillations and even erasing of the polariton density by optical pulses. The data are reproduced by a quantum optical model with excellent accuracy, providing new insights on the key components that rule the polariton dynamics.

摘要

我们报告了在微腔中对空间和时间分辨的光与物质拉比振荡的实验观测与控制。我们的装置精度和系统相干性极高，以至于可以通过光脉冲放大或关闭振荡，甚至消除极化激元密度来实现相干控制。量子光学模型以极高的精度再现了这些数据，为支配极化激元动力学的关键组件提供了新的见解。
