结构化的等离子体超材料器件提供了设计灵活性，以在整个电磁频谱上进行操作的尺寸缩放，并且对于经由亮和暗亚波长谐振器的耦合来产生电磁感应透明性和慢光行为是非常有吸引力的。在这里，我们实验证明了一个热激活的超导金属耦合谐振器为基础的混合太赫兹超材料的蓝宝石衬底上，显示可调的透明度和慢光行为的超材料芯片冷却到高温超导相变温度以下。这种混合超材料为设计具有开关、调制和“减慢太赫兹光”能力的微型有源电路开辟了道路。
Structured plasmonic metamaterial devices offer the design flexibility to be size scaled for operation across the electromagnetic spectrum and are extremely attractive for generating electromagnetically induced transparency and slow-light behaviors via coupling of bright and dark subwavelength resonators. Here, we experimentally demonstrate a thermally active superconductor-metal coupled resonator based hybrid terahertz metamaterial on a sapphire substrate that shows tunable transparency and slow light behavior as the metamaterial chip is cooled below the high-temperature superconducting phase transition temperature. This hybrid metamaterial opens up the avenues for designing micro-sized active circuitry with switching, modulation, and “slowing down terahertz light” capabilities.
