In-Fiber Subpicosecond Pulse Shaping for Nonlinear Optical Telecommunication Data Processing at 640 Gbit/s

<table>Flat-top pulses and 640 Gbit/s demultiplexing with subpicosecond flat-top pulse. Top: measured cross-correlation traces of the generated flat-top pulses of various widths and deconvoluted waveforms. Bottom: BER performance with and without flat-top pulse. Insets show the spectral (lower left) profile of the flat-top pulse and the temporal (upper right) corresponding waveforms of the flat-top super-Gaussian (or order <svg height="11.375" id="M59" style="vertical-align:-0.1638pt" version="1.1" viewbox="0 0 45.0625 11.375" width="45.0625" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
