Paper Abstract

A magnetic field sensor based on a Mach-Zehnder interferometer with standard single mode fiber (SMF-28) is proposed. Here, the MZI was developed by using tapered optical fiber technique. Moreover, the Mach-Zehnder interferometer is manufactured with two tapers, with a core diameter of 25~40 μm and a length of 5 mm, and a separation between the tapers about of 4~6.5 cm. The MZI was covered by a fluid with magnetic proprieties. Performing experiments with magnets, coils and transformers, hoping that the proposed sensor offers a good option to measure the magnetic field in electrical devices.
