本文介绍了一种基于集总元件超导谐振器（LEKID）的新型FIR检波器。这些器件可以用作分布式FIR辐射吸收器，而不需要额外的耦合结构。此外，这些器件可以集成到具有高填充因子的紧凑填充阵列几何结构中。我们描述了集总元件谐振器的优化，以获得对200μm - 450μm波长范围内入射辐射的高耦合效率，这些器件的电学和光学特性的测量以及使用这些探测器的原型阵列的设计。
We describe a new type of FIR detector based on lumped element superconducting resonators (LEKIDs). These devices can act as distributed FIR radiation absorbers without the need for an additional coupling structure. In addition, these devices can be integrated into a compact filled array geometry with high filling factor. We describe the optimization of lumped element resonators for high coupling efficiency to incoming radiation in the wavelength region from 200μm - 450μm, measurements of electrical and optical properties of these devices and the design of a prototype array using these detectors.
