Time-Limited Waveforms With Minimum Time Broadening for the Nonlinear Schrödinger Channel

Simple fiber optic communication systems can be implemented using energy modulation of isolated time-limited pulses. Fundamental solitons are one possible solution for such pulses which offer a fundamental advantage: they preserve their shape along the channel. Furthermore, simple detector used at receiver to detect transmitted information. However, based on not competitive in terms data rates. This is partly due fact that effective time duration soliton depends its chosen amplitude. In this paper, we propose replace by new waveforms detected an detector, and immune distortions. Our proposed relies prolate spheroidal wave functions numerical optimization routine. Time-limited undergo minimum broadening optical obtained shown outperform solitons. case binary transmission single span fiber, report rate increases 33.8% 12% over lossy lossless fibers, respectively. show system as number levels increases, time-amplitude constraint. For example, 164% 70% fibers respectively reported when four levels.
