论文摘要
我们证明了如何使用hong-ou-mandel（HOM）干扰具有极化的光子的光子。我们可以推断出介质的复杂敏感性的真实和虚构的光学特性，从hom倾角的位置和形状变化而变化。从HOM DIP的转移中，我们也能够使用连续波（CW）激光量> 97％的连续波（CW）激光测量22 fs的时间，而HOM DIP可见性保持在92.3〜 \％（可以高达96.7％）。通过严格的理论模型来解释的实验观察结果表明，HOM干扰在探测超快dephasing方面的实用性。
We demonstrate how the Hong-Ou-Mandel (HOM) interference with polarization-entangled photons can be used to probe ultrafast dephasing. We can infer the optical properties like the real and imaginary parts of the complex susceptibility of the medium from changes in the position and the shape of the HOM dip. From the shift of the HOM dip, we are able to measure 22 fs dephasing time using a continuous-wave (CW) laser even with optical loss > 97%, while the HOM dip visibility is maintained at 92.3~\% (which can be as high as 96.7%). The experimental observations, which are explained in terms of a rigorous theoretical model, demonstrate the utility of HOM interference in probing ultrafast dephasing.
