Optical Fiber Sensing is a technology that uses optical fibers to detect and measure physical, chemical, or environmental parameters by exploiting changes in light properties as they propagate through the fiber. Optical fibers are highly sensitive to various external factors, making them valuable for sensing applications in industries such as telecommunications, oil and gas, healthcare, and environmental monitoring.
We propose a single-ended Brillouin-based sensor in elliptical-core few-mode optical fiber for multi-parameter measurement using spontaneous Brillouin scattering. Distributed sensing of temperature and strain is demonstrated over 0.5 km elliptical-core few-mode fiber.
