Abstract: Space Division Multiplexing aims to use the multiple modes of optical fibers to improve the performance of communications systems. This talk will describe various components that enable space division multiplexing, such as mode multiplexers supporting over 45 spatial modes, amplifiers, and some digital signal processing techniques. In addition, we will show some devices we have made that can control space-time-polarization and wavelength.
I will also show a brief laboratory tour of where I work at Nokia Bell Labs.
Biography: 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.
