3D Waveguide and All-Fiber 'Photonic Lantern Spatial Multiplexers
27 August 2014
Space-division multiplexing requires spatialmultiplexers 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.
