Multi-spot based mode (de)multiplexer for mode division multiplexing over few-mode fiber

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademic


Multiple-Gaussian-spot based mode multiplexers are investigated in this paper for Mode Division Multiplexing over Few-mode Fiber. A structure of five spots for exciting 3 spatial modes: LP01 and degenerate LP11 with high mode extinction ratio is discussed and realized by a silicon-on-insulator integrated circuit. Test results are presented. Moreover, a spot-based solution scalable to support more modes is introduced and simulated. It is demonstrated low insertion loss and mode-dependent loss can be achieved but with sacrificing mode extinction ratio. A variety of compact solutions can be used to realize these multi-spot schemes, such as photonic integration, photonic lantern and 3D-waveguide.
