论文摘要
动力学电感探测器(KID)在天文观测中具有巨大的潜力,例如搜索系外行星,因为它们的噪声低,快速响应和光子计数特征。在本文中,我们介绍了微带线耦合的儿童阵列的设计过程和模拟结果,以进行近红外的天文观察。与共面波导(CPW)饲养场相比,微带馈线不需要空气桥,这简化了制造过程。在设计部分中,我们主要关注阻抗转换网络,孩子结构和频率串扰模拟。测试阵列共有104个谐振器,有8行和13列,范围从4.899〜GHz到6.194〜GHz。音高大小约为200〜 $μ$ m,模拟中的频率串扰小于50〜 kHz。
Kinetic inductance detectors (KID) have great potential in astronomical observation, such as searching for exoplanets, because of their low noise, fast response and photon counting characteristics. In this paper, we present the design process and simulation results of a microstrip line coupled KIDs array for near-infrared astronomical observation. Compared with coplanar waveguide (CPW) feedlines, microstrip feedlines do not require air bridges, which simplify fabrication process. In the design part, we mainly focus on the impedance transforming networks, the KID structure, and the frequency crosstalk simulations. The test array has a total of 104 resonators with 8 rows and 13 columns, which ranges from 4.899~GHz to 6.194~GHz. The pitch size is about 200~$μ$m and the frequency crosstalk is less than 50~kHz in simulation.
