| Research Abstract |
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.
