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.

该实验研究计划利用了新兴能力研究半导体纳米系统（腔/点），其中单个量子发挥了决定性作用。该计划是要看到量子性兔振荡的影响要清晰得多。即使单个量子点的水平过渡与原子相似，但在半导体中仍存在库仑效应。他们可能会像量子井微腔一样提供有趣的曲折。光子/点纠缠的观察将很重要。提出的是飞秒脉冲和连续波梁的共鸣和非谐振激发。简而言之，这种新结构将被激发，并以所有可能的方式检测到其响应：改变功率并寻找从量子到半经典制度的过渡，测量相关性，折叠时间，激光阈值和光学双重性波动。该计划的更广泛影响涉及纳米光子行业的教育以及应用。
