Abstract
In presented work, the tunable characteristics of magnetic fluid refractive index under the influence of magnetic field with single mode fiber (SMF) with tapered structure are investigated. The sensing fiber probe consists of special down taper joints formed by fusion splicer. Experimental result indicates that the proposed device has excellent magnetic fluid refractive index tunability. The sensitive performances of the sensors are controlled by designing the parameters of the tapered structure and the concentration of Magnetic fluid. Experimental result used to carry out to achieve the magnetic field (intensity and direction) dependent refractive index of the magnetic fluid.
