Digital Compensation of SOA-Induced Nonlinearities in Field-Modulated Direct-Detection Systems

In this work we experimentally demonstrate the compensation of nonlinearities introduced by a semiconductor optical amplifier (SOA) operating as a power booster in a field-modulated direct detection fiber-optic system transmitter. We show that a combination of digital <italic>pre</italic>...
