Abstract Spintronics and Photonics constitute separately two disciplines of huge scientific and technological impact. Exploring their conceptual and practical overlap offers vast possibilities of research and a clear scope for the corresponding communities to merge and consider innovative ideas taking advantage of each other’s potentials. As an example, here we review the magnetic field modification of the optical response of photonic systems fabricated out of spintronic materials, or in which spintronic components are incorporated. This magnetic actuation is due to the Magneto Refractive Effect (MRE), which accounts for the change in the optical constants of a spintronic system due to the magnetic field induced modification of the electrical resistivity. Due to the direct implication of conduction electrons in this phenomenon, this change in the optical constants covers from the mid-infrared to the THz regime. After introducing the non-expert reader into the spintronic concepts relevant to this work, we then present the MRE exhibited by a variety of spintronic systems, and finally show the different applications of this property in the generation of active spintronic-photonic platforms.

使用自旋电子结构的中红外到太赫兹区域的有源光子平台

摘要 自旋电子学和光子学分别构成两个具有巨大科技影响的学科。探索它们在概念和实践上的重叠提供了广阔的研究可能性，并为相应的社区合并和考虑利用彼此潜力的创新想法提供了明确的范围。作为一个例子，我们在这里回顾了由自旋电子材料制造的光子系统的光学响应的​​磁场修改，或者其中包含自旋电子元件。这种磁驱动是由磁折射效应 (MRE) 引起的，它解释了由于磁场引起的电阻率修改而导致自旋电子系统的光学常数发生变化。由于传导电子在这种现象中的直接含义，光学常数的这种变化涵盖了从中红外到太赫兹区域。在向非专家读者介绍与这项工作相关的自旋电子概念之后，我们展示了各种自旋电子系统所展示的 MRE，最后展示了该特性在有源自旋电子光子平台生成中的不同应用。
