Current-biased kinetic inductance detectors (CB-KIDs) proposed by the authors have several features suitable for image sensors, though an operation of a single detector has been demonstrated so far. In this study, we tried to develop a monolithic chip on which a linear array composed of 500 CB-KIDs and a readout circuit based on the single flux quantum (SFQ) circuit are implemented. To suppress the interference between neighboring two detectors, we place low-pass filters between the detectors. When we apply an on-off modulated optical signal to the chip, a synchronized output signal is observed, suggesting that the linear array operates correctly. We will optimize circuit parameters for practical image sensors.

作者提出的电流偏置动态电感探测器 (CB-KID) 具有多种适合图像传感器的功能，尽管迄今为止已经演示了单个探测器的操作。在本研究中，我们尝试开发一种单片芯片，在该芯片上实现由 500 个 CB-KID 组成的线性阵列和基于单通量量子（SFQ）电路的读出电路。为了抑制相邻两个探测器之间的干扰，我们在探测器之间放置低通滤波器。当我们向芯片施加开关调制光信号时，会观察到同步输出信号，这表明线性阵列工作正常。我们将为实际图像传感器优化电路参数。
