A Mach–Zehnder interferometric magnetic field sensor based on a photonic crystal fiber (PCF) and magnetic fluid (MF) was designed and experimentally demonstrated. The sensing probe consists of a single-mode-(SM)multimode-PCF-SM fiber structure through arc fusion splicing. It was then laser engrave n...
