论文摘要
多维相干光谱直接揭开了在线性光谱中重叠的多激发状态。我们报告了半导体极化二极管中的多维相干光电流光谱,并探索了腔极化子的激发梯子。我们测量了对激子 - 两极分子的对和三胞胎的双重和三重交叉,证明了光和穿着的Doublet和三胞胎半导体激发之间的强耦合。这些结果表明,强烈耦合到微腔的乘激发激发型状态可以描述为两个耦合的量子 - 动物梯子。
Multidimensional coherent spectroscopy directly unravels multiply excited states that overlap in a linear spectrum. We report multidimensional coherent optical photocurrent spectroscopy in a semiconductor polariton diode and explore the excitation ladder of cavity polaritons. We measure doubly and triply avoided crossings for pairs and triplets of exciton-polaritons, demonstrating the strong coupling between light and dressed doublet and triplet semiconductor excitations. These results demonstrate that multiply excited excitonic states strongly coupled to a microcavity can be described as two coupled quantum-anharmonic ladders.
