Abstract

In this paper, we propose a simplified approach to optical signal predistortion based on adaptive pulse shaping through asymmetrical control of a Mach-Zehnder modulator above its switching voltage. The scheme allows natural tailoring of transmitted pulses by optimizing the received pulse. We demonstrate enhancement of the power tolerance in nonrepeated systems and improved OSNR/BER performance and dispersion tolerance in ultra-long-haul fiber systems operating at 10 Gb/s and 20 Gb/s channel rates. The improved performance is demonstrated through simulations and experiment.
