3D waveguide and all-fiber “photonic lantern” spatial multiplexers

摘要

Space-division multiplexing requires spatial-multiplexers that support over 10 modes with low insertion loss and low mode-dependent loss. Photonic lantern spatial multiplexers provide a lossless interface between N single-mode fibers and the N modes of a multi-mode fiber. Devices fabricated using all-fiber technology and 3D waveguide technology have enabled transmission in multi-mode fibers supporting 12 spatial and polarization modes.
