摘要:

提出了一种通过直接测量热场强度并离线分析其空间起伏来寻找热场二维空间模式的方法。利用这种方法,我们以一种简单而有效的方式重建了多模光纤的模式和压缩真空的空间施密特模式,通过高增益参量下转换产生。重构的形状与理论结果一致。

英文摘要:

We propose a method for finding 2D spatial modes of thermal field through a direct measurement of the field intensity and an offline analysis of its spatial fluctuations. Using this method, in a simple and efficient way we reconstruct the modes of a multimode fiber and the spatial Schmidt modes of squeezed vacuum generated via high-gain parametric down conversion. The reconstructed shapes agree with the theoretical results.
