Selective excitation of a diffusive system’s transmission eigenchannels enables manipulation of its internal energy distribution. The fluctuations and correlations of the eigenchannel’s spatial profiles, however, remain unexplored so far. Here we show that the depth profiles of high-transmission eigenchannels exhibit low realization-to-realization fluctuations. Furthermore, our experimental and numerical studies reveal the existence of interchannel correlations, which are significant for low-transmission eigenchannels. Because high-transmission eigenchannels are robust and independent from other eigenchannels, they can reliably deliver energy deep inside turbid media.

扩散介质中本征通道的波动与相关

扩散系统的传输本征通道的选择性激发能够操纵其内部能量分布。然而，本征通道空间分布的波动和相关性至今仍未得到探索。在这里，我们表明，高传输特征信道的深度剖面显示出较低的实现间波动。此外，我们的实验和数值研究揭示了通道间相关性的存在，这对于低透射本征通道很重要。因为高传输本征通道很健壮并且独立于其他本征通道，所以它们可以可靠地将能量传递到混浊介质内部。
