Beam splitters are an indispensable part of optical measurements and applications. We propose a dynamic beam splitter incorporating all-dielectric metasurface in an elastic substrate under external mechanical stimulus of stretching. The optical behavior at 720 nm wavelength shows that it can be changed from a pure optical-diode-like behavior to a dynamic beam splitter. Although the structure is designed running at 720 nm, the design approach with appropriate materials can be used at any wavelength. Various cases, including wavelength and polarization dependencies, are thoroughly investigated to demonstrate the principles of operating conditions of two different regimes of the designed metasurface.

使用基于弹性基底的全介电超表面的动态分束器。

分束器是光学测量和应用中必不可少的部分。我们提出了一种动态的分束器，它在外部机械刺激作用下，将全电介质超表面结合在弹性基底中。在720 nm波长处的光学行为表明，它可以从类似纯光电二极管的行为变为动态分束器。尽管该结构被设计为在720 nm下运行，但是采用适当材料的设计方法可以在任何波长下使用。彻底研究了各种情况，包括波长和偏振相关性，以证明所设计的超颖表面的两种不同状态的工作条件原理。
