Spin-controlled photonics via temporal anisotropy

Carlo Rizza, Giuseppe Castaldi, Vincenzo Galdi

摘要:

基于时变本构特性的时间超材料为先进的场操纵提供了新的可能性。在这项研究中,我们探索的能力,各向异性的时间板,它依赖于突然变化的时间从各向同性到各向异性的响应(反之亦然)。我们的研究结果表明,这些平台可以有效地操纵波自旋维度,允许一系列有趣的自旋控制光子操作。我们证明了这些能力,通过自旋相关的模拟计算和自旋轨道相互作用的影响,涡流的产生的例子。这些结果为时间超材料领域提供了新的见解,并在通信,光学处理和量子技术中提出了潜在的应用。

英文摘要:

Temporal metamaterials, based on time-varying constitutive properties, offer new exciting possibilities for advanced field manipulations. In this study, we explore the capabilities of anisotropic temporal slabs, which rely on abrupt changes in time from isotropic to anisotropic response (and vice versa). Our findings show that these platforms can effectively manipulate the wave-spin dimension, allowing for a range of intriguing spin-controlled photonic operations. We demonstrate these capabilities through examples of spin-dependent analog computing and spin-orbit interaction effects for vortex generation. These results provide new insights into the field of temporal metamaterials, and suggest potential applications in communications, optical processing and quantum technologies.
