In article number 2006489, Tian Jiang and co‐workers propose bifunctional spatiotemporal terahertz metasurfaces, which perform versatile, ultrafast terahertz switching behaviors at continuously alterable resonant states. The incident‐angle tunable EIT/LC resonance can be effectively switched‐off by means of photon injection.
Advances in tunable metamaterials/metasurfaces facilitates their utilization in novel optical components, and lead to many breakthroughs in light tailoring by giving birth to diverse spatiotemporal dynamics. In the ascendant field of terahertz (THz) photonics, the ultrafast modulation is the fundamental process of technological advancements in high‐speed wireless communications, sensing, and imaging...
Optoelectronic terahertz switching achieved by dynamically tuning metamaterials is viewed as a major breakthrough in promoting the advancement of terahertz technology. However, the main thrust toward the development of ultrafast switchable components and optical logic operations is still in a catch‐up stage for progressively increasing information and communication demands. Here, a novel spatiotemporal...
Recently, the actively controlled meta‐atoms have been employed to manipulate terahertz (THz) waves allowing for the implementation of many functionalities operating. A salient example of such systems is the electromagnetically induced transparency (EIT) metaphotonic device, which opens up a new avenue for THz manipulations. However, these devices are currently limited to be tuned at a given frequency,...
