论文摘要
多平面光转换允许对有限的空间模式进行任意转换，而没有理论上限制转换质量。即使形状模式的数量通常很小，但多面光转换器（MPLC）传输的模式的数量也极大。在这项工作中，我们旨在表征内部多平面灯转换器的传输属性，并首次在设计模式子空间之外。通过数值重建此类系统的传输矩阵，我们个性化的方法来评估它们在执行设计转换方面的效率。此外，我们开发了一个分析随机矩阵模型，该模型表明，在大量形状模式的状态下，MPLC的行为就像是随机散射培养基，受控通道数量有限。
Multi-plane light conversion allows to perform arbitrary transformations on a finite set of spatial modes with no theoretical restriction to the quality of the transformation. Even though the number of shaped modes is in general small, the number of modes transmitted by a multi-plane light converter (MPLC) is extremely large. In this work, we aim to characterize the transmission properties of a multi-plane light converter inside and, for the first time, outside the design-modes subspace. By numerically reconstructing the transmission matrix of such systems, we individuate new ways to evaluate their efficiency in performing the design transformation. Moreover, we develop an analytical random matrix model that suggests that in the regime of a large number of shaped modes an MPLC behaves like a random scattering medium with limited number of controlled channels.
