提出了一种新型的分布式滤波光纤，在要求的波长处芯层和包层之间具有谐振耦合。通过对几种光纤的仿真，说明了设计原理。按照这种设计策略制作了过滤纤维。透射光谱测量和模式输出成像证实了在1100nm附近芯层和包层之间的谐振耦合。
A new type of fiber for distributed filtering is proposed, designed to have resonant coupling between core and cladding at desired wavelengths. Design principles are illustrated with simulations of several fibers. A filter fiber was fabricated following this design strategy. Measured transmission spectra and imaging of mode output confirm the expected resonant coupling between core and cladding near 1100nm.
