摘要：
An all-fiber magnetic-field sensor combining a multicore fiber taper and magnetic fluid is proposed and experimentally demonstrated. The magnetic-field sensing mechanism is investigated theoretically and experimentally. Experimental results demonstrate that the dip-wavelength of the proposed sensor regularly varies with the changes of the applied magnetic field. The measuring sensitivity is achieved to be similar to 34 pm/Gs in the magnetic induction intensity range of 50-300 Gs. Moreover, the sensor responding to the 50-Hz alternating magnetic field is also experimentally investigated, and a minimal detectable magnetic induction intensity of similar to 23.7 Gs is successfully achieved. The proposed magnetic field sensor is attractive due to its compact size, low cost, and immunity to electromagnetic interference.
