Abstract: This paper presents an analysis of the semiconductor optical amplifier (SOA) on coherent optical orthogonal frequency division multiplexing system (CO-OFDM), when it is used as a booster power amplifier. The semiconductor optical amplifier is driven by their bias current injection, which control the amplification level. In this sense, this study analyses the impact of bias current change on a SOA based CO-OFDM system. It is well known that SOA is prone to nonlinear distortion when high input power is used at high gain level, because the gain saturation. In addition to the aforementioned analysis, here it is also presented three operation scenarios to characterize the performance of the system: maximum EVM equal to 20%, constant output power equal to -7 dBm, and constant SOA Gain equal to 17 dB. This let us obtain a way to optimize the SOA performance, under each scenario, controlling the bias current.
