锥形过渡可以在多模光纤和若干单模光纤之间耦合光。如果单模光纤的数量与多模光纤中的空间模式的数量匹配，则过渡可以在两个方向上具有低损耗。这使得单模光纤器件的高性能能够在多模光纤中实现。我们报告了一个实验证明的概念，通过使用光子晶体光纤技术，使过渡，演示了多模光纤滤波器的单模光纤光栅的透射谱。
A taper transition can couple light between a multimode fiber and several single-mode fibers. If the number of single-mode fibers matches the number of spatial modes in the multimode fiber, the transition can have low loss in both directions. This enables the high performance of single-mode fiber devices to be attained in multimode fibers. We report an experimental proof of concept by using photonic crystal fiber techniques to make the transitions, demonstrating a multimode fiber filter with the transmission spectrum of a single-mode fiber grating.
