Unique and flexible properties of non-Hermitian photonic systems attract ever-increasing attention via delivering a whole bunch of novel optical effects and allowing for efficient tuning light-matter interactions on nano- and microscales. Together with an increasing demand for the fast and spatially compact methods of light governing, this peculiar approach paves a broad avenue to novel optical applications. Here, unifying the approaches of disordered metamaterials and non-Hermitian photonics, we propose a conceptually new and simple architecture driven by disordered loss-gain multilayers and, therefore, providing a powerful tool to control both the passage time and the wave-front shape of incident light with different switching times. For the first time we show the possibility to switch on and off kink formation by changing the level of disorder in the case of adiabatically raising wave fronts. At the same time, we deliver flexible tuning of the output intensity by using the nonlinear effect of loss and gain saturation. Since the disorder strength in our system can be conveniently controlled with the power of the external pump, our approach can be considered as a basis for different active photonic devices.

非赫米特光子系统的独特而灵活的特性通过提供一整套新颖的光学效果并允许在纳米和微米尺度上有效地调节光-物质相互作用，吸引了越来越多的关注。加上对光控制的快速和空间紧凑的方法的日益增长的需求，这种奇特的方法为新型光学应用铺平了广阔的道路。在这里，统一无序超材料和非赫米特光子学的方法，我们提出了一种由无序损耗增益多层驱动的概念上新颖且简单的体系结构，因此，提供了一个强大的工具来控制光的通过时间和波前形状入射光具有不同的切换时间。我们首次展示了在绝热地上升波阵面的情况下，通过改变无序水平来打开和关闭扭结形成的可能性。同时，我们利用损耗和增益饱和的非线性效应，灵活地调节输出强度。由于我们系统中的无序强度可以通过外部泵的功率方便地控制，因此我们的方法可以被视为不同有源光子器件的基础。
