我们提出了一种新的长周期光纤光栅，可用于光纤内、低损耗、带阻滤波。写入标准通信级光纤芯部的光致周期性结构将来自基本导模的光耦合到前向传播包层模，并用作光谱选择性损耗元件，插入损耗为0.2dB，巴克反射损耗为-80db，偏振模色散为0.01ps，偏振相关损耗为0.02db。
We present a new class of long-period fiber gratings that can be used as in-fiber, low-loss, band-rejection filters. Photoinduced periodic structures written in the core of standard communication-grade fibers couple light from the fundamental guided mode to forward propagating cladding modes and act as spectrally selective loss elements with insertion losses < 0.2 dB, barkreflections < -80 dB, polarization-mode-dispersions < 0.01 ps and polarization-dependent-losses < 0.02 dB.
