| 摘 要： | 报导了一种钇钡铜氧（YBCO）高温超导薄膜中远红外光探测器。在中远红外波段，利用北京自由电子激光对其响应特性进行了实验研究。对于微桥尺寸为210μm×70μm×0.3μm的样品,测量了电压响应、谱响应和时间响应。实验表明，在液氮温度下工作的YBCO高温超导光探测器不仅具有快速响应、较高灵敏度的特点，而且具有良好的宽带特性和较好的稳定性。

| Abstract: | A middle to far infrared detector, which uses a YBCO high temperature superconductive thin film, was introduced. The research on its middle to far infrared response characteristics was conducted by utilizing the Beijing Free Electronic Laser. The micro-bridge size of the test target is 210 μm×70 μm×0.3 μm and its voltage, spectrum, and time responses are measured. Results show that the YBCO high temperature superconductive light detector, which works under the temperature of liquid nitrogen, has properties of fast response, high sensibility, good wide bandwidth and good stability. |
