我们提出了微弯长周期光纤光栅，可以用作电损耗可调带阻滤波器。波长选择损耗的可调性是基于电磁铁和钢卷弹簧对光纤的可变扰动。得到的动态损失幅度为11 dB，测量的响应时间为16 ~ 18 ms。
We present microbend long-period fiber gratings that can be used as electrically loss-tunable band-rejection filters. The tunability of wavelength-selective loss is based on variable perturbation of the fiber induced by an electromagnet in combination with a steel coil spring. A dynamic loss amplitude of 11 dB is obtained and the response time measured is 16-18 ms.
