摘要：

The polarization properties of photorefractive reflection gratings formed in Ge-doped hi-bi fibers by the internal method are presented. The gratings reflect only the polarization eigenmode used in fabrication and a polarization selectivity of 20 dB is demonstrated. It is also shown that there are two different photorefractive effects that can be used to write the gratings: one is permanent when heated to 240-degrees-C, while the other is erasable.
