我们实验研究了从几个原子到量子阱导模的共振荧光中的光子关联。结果表明，当光子沿同一方向发射时，随着原子数的增加，光子关联从反聚束变为聚束;当光子沿相反方向发射时，无论原子数多少，光子关联总是反聚束的.讨论了激发几何对光子关联的影响。
We experimentally investigate the photon correlations in resonance fluorescence from a few atoms into the guided modes of the nanofiber. We show that, when the photons are emitted in the same direction, the photon correlation varies from antibunching to bunching with increasing atom number and, when the photons are emitted in the opposite directions, the photon correlation is always antibunchinglike regardless of the number of atoms. The effect of excitation geometry on the photon correlations is also discussed.
