Impact on Fiber Design on Polarization Dependence in Microbend Gratings
05 September 2005
Polarization dependence in microbend gratings is an inherent problem. We formulate simple analytical expressions to describe it, and demonstrate their effectiveness via a comparison with experimental results on a standard transmission fiber. The ability to control polarization dependence with fiber design potentially enables replacing UV-LPGs within low-cost tunable microbend gratings.
