Space-division multiplexed (SDM) systems use the multiple spatial modes in either multi-core fiber (separated modes), or the spatially overlapping but orthogonal modes in few-mode fibers to either increase the capacity or photon-efficiency of fiber links.The new challenges in SDM are how to couple into and out of the various SDM fibers without insertion loss (IL) or mode-dependent loss (MDL), and building components that have comparable performance to, and that offer a cost advantage over systems using multiple single-mode fibers.  I will show several components for space-division multiplexing in few-mode fibers including "photonic lantern" spatial multiplexers which are lossless adiabatic single-mode to multi-mode converters, and wavelength selective switches for routing signals in few-mode fiber. These components enable transmission of signals across multi-mode fiber using up to 12 spatial and polarization modes.

Nicolas Fontaine obtained his Ph. D. in 2010 at the University of California, Davis in the Next Generation Network Systems Laboratory [] in Electrical Engineering. In his dissertation he studied how to generate and measure the amplitude and phase of broadband optical waveforms in many narrowband spectral slices. Since June 2011, he has been a member of the technical staff at Bell Laboratories at Crawford Hill, NJ in the advanced photonics division.  At Bell Labs, he develops devices for space-division multiplexing in multi-core and few mode fibers, builds wavelength crossconnects and filtering devices, and investigates spectral slice coherent receivers for THz bandwidth waveform measurement. Nicolas Fontaine has been author or co-author on over 100 publications, including several post-deadline and invited papers at OFC, ECOC, and CLEO.
