A method to induce only one permanent and localized dynamic Brillouin grating in polarization maintaining optical fibers is introduced. The generation of the grating exploits the thumbtack correlation of the chaotic laser signals. A numerical calculation, corroborated by a theoretical analysis, is performed and the grating properties, length, and reflectance determined.
介绍了一种在保偏光纤中仅诱导一个永久且局域性的动态布里渊光栅的方法。该光栅的产生利用了混沌激光信号的图钉相关特性。进行了数值计算，并通过理论分析进行了验证，确定了光栅的特性、长度和反射率。
