Abstract
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.
Biography
Nicolas Fontaine obtained his Ph. D. in 2010 at the
University of California, Davis in the Next Generation Network Systems
Laboratory [http://sierra.ece.ucdavis.edu]
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.
