用少芯耦合器演示了多模光纤空间模式的复用和解复用。模式组合/分离是通过模式选择的倏逝耦合实现的。特别地，三种光纤模式的多路复用器/解路复用器被模拟使用圆形（光纤）或矩形（平面）芯。通过明智地选择芯结构，可以使解复用与光纤模式的空间方向无关。
The multiplexing and demultiplexing of the spatialmodes of few-mode fiber is demonstrated using few-core couplers. The mode combination/separation is achieved through mode-selective evanescent coupling. In particular, multiplexers/demultiplexers for three fiber modes are simulated that use either circular (fiber) or rectangular (planar) cores. The demultiplexing can be made independent of the spatial-orientations of the fiber modes by judicious choice of core configuration.
