  • Design and performance of an extrinsic guided wave fiber optic magnetic field sensor is reported. The sensor utilizes a substituted YIG (yttrium iron garnet, Y3Fe5O12) thin film as the waveguiding sensing element. A polarization maintaining fiber downlead was used to provide insensitivity to both power and loss fluctuations. The design makes it possible to determine both the magnitude and the sign of the magnetic field. Measurement results indicate a usable measurement range of at least several mT with a noise equivalent magnetic field level of less than 8 nT/√Hz
