Distributed Fluorescence Sensing Using Exposed Core Microstructured Optical Fiber

Fluorescence-based distributed sensing using exposed core microstructured optical fiber has been demonstrated. The optical fiber consists of a suspended optical micro-wire surrounded by a solid jacket, a portion of which is absent to allow access to the evanescent field from the external environment. We demonstrate time-domain distributed sensing by immersing different sections of the fiber in a fluorescent liquid.
