Highly Sensitive Optical Fiber MZI Sensor for Specific Detection of Trace Pb²⁺ Ion Concentration

Photonics
A novel chitosan (CS) functionalized optical fiber sensor with a bullet-shaped hollow cavity was proposed in this work for the trace concentration of Pb2+ ion detection in the water environment. The sensor is an optical fiber Mach–Zehnder interferometer (
