论文摘要
非临界元素是电气和光学系统的重要组成部分。在红外制度中，对破坏互惠的结构特别感兴趣，因为它们的热吸收性（和发射）特性不应遵守Kirchhoff热辐射法。在这项工作中，我们打破了N型掺杂的磁磁体iNAS中的时间倒流对称性和互惠性，并带有静态磁场，在该磁场中，光耦合由指导模式谐振器（GMR）结构介导，其共振频率与Epsilon-Near-Near-Near-Near-near-Zer-Zer-Zer-Zer-Zer-Zer-Zerance Resonance nosance insas insas insas insas insas insas insas insas insas resonant介导。使用这种结构，我们观察到非邻次吸收行为是红外磁场和散射角的函数。考虑到谐振和非谐振光学散射，我们可靠地模拟了破坏红外相互吸收关系的实验结果。设计此类非偏射吸收器的能力为在特定渠道中具有不平等的吸收性和发射率不平等的设备开辟了途径。
Nonreciprocal elements are a vital building block of electrical and optical systems. In the infrared regime, there is a particular interest in structures that break reciprocity because their thermal absorptive (and emissive) properties should not obey the Kirchhoff thermal radiation law. In this work, we break time-reversal symmetry and reciprocity in n-type doped magneto-optic InAs with a static magnetic field where light coupling is mediated by a guided-mode-resonator (GMR) structure whose resonant frequency coincides with the epsilon-near-zero (ENZ) resonance of the doped InAs. Using this structure, we observe the nonreciprocal absorptive behavior as a function of magnetic field and scattering angle in the infrared. Accounting for resonant and nonresonant optical scattering, we reliably model experimental results that break reciprocal absorption relations in the infrared. The ability to design such nonreciprocal absorbers opens an avenue to explore devices with unequal absorptivity and emissivity in specific channels.
