论文摘要
我们介绍并实验证明了一类新的电气驱动的热发射器，基于全球对齐的碳纳米管的纳米材料的纳米材料，以纳米级丝带形成。超材丝带具有极端各向异性的电子和光子性能，沿着一个轴可实现低损耗，波长压缩双曲线光子模式，高电阻率和高电阻率以及沿另一个轴的有效焦耳加热。设备在单个芯片发射的线性极化热辐射上进行了批量制造，其峰值波长由其双曲线共振指示，其低热量质量产生的红外辐射调节速率高达1兆赫。作为概念验证的演示，我们表明，单个芯片上的两组热发射器，每个芯片上的光谱峰位置和调制速率不同，可用于感知使用单个检测器的二氧化碳。我们预计，与基于双曲芯片的热发射器的批处理制造，宽调制带宽和定制光谱调整的结合将使多重红外源的新模式用于传感，成像和计量应用。
We introduce and experimentally demonstrate a new class of electrically driven thermal emitter based on globally aligned carbon nanotube metamaterials patterned as nanoscale ribbons. The metamaterial ribbons exhibit electronic and photonic properties with extreme anisotropy, which enable low loss, wavelength-compressed hyperbolic photonic modes along one axis and high electrical resistivity and efficient Joule heating along the other axis. Devices batch-fabricated on a single chip emit linearly polarized thermal radiation with peak wavelengths dictated by their hyperbolic resonances, and their low thermal mass yields infrared radiation modulation rates as high as one megahertz. As a proof-of-concept demonstration, we show that two sets of thermal emitters on a single chip, each operating with different spectral peak positions and modulation rates, can be used to sense carbon dioxide with a single detector. We anticipate that the combination of batch fabrication, wide modulation bandwidth, and customized spectral tuning with hyperbolic chip-based thermal emitters will enable new modalities in multiplexed infrared sources for sensing, imaging, and metrology applications.
