Abstract
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.
