The controllability of photonic setups is strongly related to how coherently their outputs react to changes in their inputs; such a generic concept is treated in the case of films comprising multilayers of tilted optical axes, under visible light. The optimized designs incorporate ordinary metals or semiconductors while being able to achieve practically all the combinations of reflected, transmitted and absorbed power within the passivity limits. Importantly, most of the proposed structures exhibit substantial robustness to manufacturing defects and are fabricable with various methods. Therefore, they can make indispensable pieces of integrated photonic systems by improving their light-controlling operation for applications ranging from steering and electrodynamic switching to filtering and optical signal processing.
光子装置的可控性与它们的输出对输入变化的相干反应方式密切相关；在可见光下，对于由倾斜光轴多层组成的薄膜情况，会探讨这样一个通用概念。优化设计包含普通金属或半导体，同时能够在无源极限内实现反射、透射和吸收功率的几乎所有组合。重要的是，大多数所提出的结构对制造缺陷具有很强的鲁棒性，并且可以用各种方法制造。因此，通过改进其光控操作，它们可以成为集成光子系统中不可或缺的部件，应用范围从光控和电动开关到滤波和光信号处理。
