InP-based optical memory with the concept of metamaterial

光学超材料为介电常数ε和磁导率μ等电磁参数设计领域的创新提供了新的机遇。主要关注的焦点是创造具有独特的ε-μ值的人工材料，这种材料在任何现有介质中都无法观察到，并利用这些扩展参数来更好地控制电磁波。下一个趋势是将超材料视为设备，其中金属的结构和与功能剂的杂交带来了新的功能。特别是，将光学超材料引入实际的光子器件是一个令人兴奋的挑战。在这项研究中，我们展示了基于inp的光学器件与超材料的结合，以展示在半导体光子平台上控制磁导率的可能性。作为一个实际的例子，我们报告了一个电驱动的磁导率控制光开关，它显示了在基于半导体的实际光子器件中同时使用介电常数和磁导率的巨大前景。

Optical metamaterials offer new opportunities for innovation in the field of electromagnetic parameter design, such as the design of permittivity ε and permeability μ. The major focus of attention is to create artificial materials with unique ε-μ values that cannot be observed in any existing media and to take advantage of these expanded parameters for better control of electromagnetic waves. One of the next trends is to think of metamaterials as devices, where the structuring of metal and the hybridization with functional agents brings new functionality. Especially, introducing optical metamaterials into actual photonic devices poses an exciting challenge.In this study, we demonstrate InP-based optical devices combined with metamaterials to show the possibility of permeability control on the semiconductor-based photonics platform. As an actual example, we report an electrically-driven permeability-controlled optical switch, which shows great promise for using both the permittivity and permeability in semiconductor-based actual photonic devices.
