| Abstract(in English) | Microbend-induced long period fiber gratings are loss- and wavelength-tunable and can be reconfigured. However, they have inherent polarization dependence due to coupling with asymmetric cladding modes under mechanical pressure. By analyzing the state of polarization, the rotation efficiency of the polarization principal axis due to the torsional fiber is changed by the stress, and the polarization ellipticity is changed simultaneously. We report that the polarization dependence can be reduced by twisting the fiber for inducing the microbend. The loss amplitude at the resonance wavelength is controlled by the combination of a coil spring and a neodymium magnet. |
