大尺寸焦平面超导体-绝缘体-超导体阵列接收器集高灵敏度、高分辨率光谱和大视场等优点于一身，在毫米/亚毫米波段的天文观测中发挥着越来越重要的作用。然而，当像素计数或像素密度增加时，基于单像素模块的积木的传统阵列构造技术变得非常困难。我们提出了一个设计概念，旨在通过平面集成阵列前端来突破这一障碍。这种方法的特点是基于薄膜的片上波导型探头和埋入式本振分布波导网。我们进行了一项概念验证研究。测量结果证明了该概念在$\Text{2}\、\Text{mm}$波长下的可行性。
Large format focal-plane superconductor-insulator-superconductor array receivers, which bring together the advantages of high-sensitivity, high-resolution spectroscopy, and broad field of view, are of growing importance in astronomical observation operating at millimeter/submillimeter wavelengths. The conventional array-construction technique based on building blocks of single-pixel modules, however, becomes prohibitively difficult when the pixel count or the pixel density increases. We frame a design concept, aiming to break through this barrier by planar-integrating the array front ends. This method features membrane-based on-chip waveguide probes and a buried-in local-oscillator distribution waveguide network. We have carried out a proof-of-concept study. The measurement results demonstrate the feasibility of the concept at $\text{2} \,\text{mm}$ wavelength.
