Thermally drawn metal-insulator-semiconductor fibers provide a scalable path to functional fibers. Here, a ladder-like metal-semiconductor-metal photodetecting device is formed inside a single silica fiber in a controllable and scalable manner, achieving a high density of optoelectronic components over the entire fiber length and operating at a bandwidth of 470 kHz, orders of magnitude larger than any other drawn fiber device.
热拉伸的金属-绝缘体-半导体纤维为功能性纤维提供了一种可扩展的途径。在这里，以可控和可扩展的方式在单根二氧化硅纤维内形成梯状金属-半导体-金属光电检测器件，在整个纤维长度上实现了高密度的光电组件，工作带宽为 470 kHz，比任何其他拉伸纤维器件都大几个数量级。
