A new all-in-fiber trace-level chemical sensing approach is demonstrated. Photoconductive structures, embedded directly into the fiber cladding along its entire length, capture light emitted anywhere within the fiber's hollow core and transform it directly into an electrical signal. Localized signal transduction circumvents problems associated with conventional fiber-optics, including limited signal collection efficiency and optical losses. This approach facilitates a new platform for remote and distributed photosensing.
一种新的全光纤痕量化学传感方法得到了验证。光电导结构直接嵌入光纤包层中，并沿着光纤的整个长度延伸，从而捕获光纤空心芯内任何位置发出的光，并将其直接转换为电信号。局部信号转换克服了传统光纤光学的一些问题，包括有限的信号收集效率和光损耗。这种方法为远程和分布式光传感提供了一个新的平台。
