We introduce an efficient method for fully characterizing multimode linear-optical networks. Our approach requires only a standard laser source and intensity measurements to directly and uniquely determine all moduli and non-trivial phases of the matrix describing a network. We experimentally demonstrate the characterization of a 6×6 fiber-optic network and independently verify the results via nonclassical two-photon interference.
我们介绍了一种用于全面表征多模线性光学网络的有效方法。我们的方法仅需要一个标准激光源和强度测量，就能直接且唯一地确定描述网络的矩阵的所有模量和非平凡相位。我们通过实验展示了对一个6×6光纤网络的表征，并通过非经典双光子干涉独立验证了结果。
