Research on a Fiber Optic Magnetic Field Sensor Based on Fuze Platform

We propose a new effective method for magnetic sensors by incorporating quantum nanosensors into the microstructure on the fiber end face. Specifically, we fabricated polymer micro tip probes containing nanodiamonds using photo induced self-writing waveguide technology. The shape of the microtips can be modulated by the curing parameters and their corresponding influence on embedded optical defects in nanodiamonds has been numerically and experimentally investigated. Based on this waveguide coupled NV fluorescence, we have found a new method for magnetic field measurement. Considering its easy to manufacture and flexible structure, it can be applied on small platforms such as fuze.
