N2 - Due to its diverse applications in photonics, bio-sensors, mechanics, etc., Mach-Zehnder interferometer becomes one of important devices. Hence, lots of efforts have been paid to develop advanced Mach-Zehnder interferometers. In this work, we explore new-model Mach-Zehnder interferometer, in which one of arm is consisted of magnetic fluid films. By utilizing the tunable refractive index of magnetic fluid films under external magnetic fields, the traveling phase of a propagating light through the magnetic fluid film is changed. This could lead to a variation in the interfered intensity of the Mach-Zehnder interferometer when an external magnetic field is applied. The modulation in the interfered intensity by the external magnetic field is demonstrated experimentally, and the relevant physical origin is also discussed.
