Abstract
The multiplexing and demultiplexing of the spatial-modes 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.
