我们描述了一种用于光频域多路复用通信系统的新型可调谐滤光器。在圆偏振态的基础上，用耦合模理论计算了磁致双折射引起的光纤Bragg光栅布拉格条件的漂移，并对石英光纤和掺Tb光纤的布拉格条件进行了比较。
We describe a novel tunable optical filter for use in optical-frequency-domain multiplexed communication systems. The shift in the Bragg condition of a fiber Bragg grating as a result of magnetically induced circular birefringence is calculated with coupled-mode theory on the basis of circular states of polarization, and the values obtained for silica and terbium-doped optical fibers are compared.
