This experimental research program capitalizes on the emerging capability to investigate a semiconductor nanosystem (cavity/dot) where individual quanta play a decisive role. The plan is to see the effects of quantum Rabi oscillations much clearer. Even though the level transitions of a single quantum dot are similar to an atom's, Coulomb effects are ever present in a semiconductor; they are likely to provide interesting twists, as they have in the quantum well microcavity. The observation of photon/dot entanglement will be important. Proposed are both resonant and nonresonant excitation by both femtosecond pulses and continuous-wave beams. In short, this new structure will be excited and its response detected in all possible ways: changing the power and looking for the transition from the quantum to the semiclassical regimes, measuring correlations, decoherence time, lasing threshold, and optical bistability fluctuations. The broader impact of the program involves education as well as applications in the nanophotonics industry.

这个实验研究计划利用新兴的能力来研究半导体纳米系统（腔/点），其中单个量子起决定性作用。该计划是为了更清楚地看到量子拉比振荡的影响。尽管单个量子点的能级跃迁类似于原子的能级跃迁，但库仑效应在半导体中始终存在;它们可能会提供有趣的扭曲，就像它们在量子阱微腔中一样。光子/点纠缠的观测将是重要的。提出了共振和非共振激发飞秒脉冲和连续波光束。简而言之，这种新结构将被激发，并以所有可能的方式检测其响应：改变功率并寻找从量子到半经典的过渡，测量相关性，退相干时间，激光阈值和光学双稳态波动。该计划的更广泛的影响涉及教育以及在纳米光子学行业的应用。
