Abstract :
Polarization dependent of fiber Mach-Zehnder interferometer is one of the factors which restrict the precision and stability of interferometer based on Mach-Zehnder structure. Making use of Jones Matrix, a propagation equation of polarization dependent fiber Mach-Zehnder interferometer was given, and then the output spectrum was shown by the propagation equation. Then an experimentally result is demonstrated to verify analysis result. It shows the calculating result is consistent with experiment. This result provides a theory guidance to analyze the influence of polarization characteristic in interferometers based on Mach-Zehnder structure. The method also can be adapted in other fiber interferometers such as fiber Michelson interferometer and so on.
