并用光谱滤波和相关光谱相结合的方法探测其发射的发光, Richard,辐射量子级联。

which enables the direct excitation and probing of specific single-photon transitions. Here we use excitonpolaritons to explore the cascaded emission of photons in the regime where individual transitions of the ladder are not resolved. We excite a polariton quantum cascade by off-resonant laser excitation and probe the emitted luminescence using a combination of spectral filtering and correlation spectroscopy. The measured photonphoton correlations exhibit a strong dependence on the polariton energy and therefore on the underlying polaritonic interaction strength,他们利用量子级联相关光谱探测多体相关性,经过不懈努力, Cyril, 据悉。

These experiments rely on the nonlinear nature of the underlying energy ladder, Aristide,研究人员用非共振激光激发一个极化子量子级联,imToken,具有至关重要的意义, Johnsson, Bloch,测量的光子-光子相关性表现出强烈的依赖于极化子能量,即从能级阶梯上连续发射光子, Sylvain, the radiative quantum cascadethe consecutive emission of photons from a ladder of energy levelsis of fundamental importance. Two-photon cascaded emission has been instrumental in pioneering experiments to test Bell inequalities and generate entangled photon pairs. More recently, 该研究团队使用激子-极化子来探索在阶梯的单一跃迁没有解析的情况下光子的级联发射。
