Abstract
In this paper, a numerical model of Semiconductor Optical Amplifiers (SOA) is
experimentally validated in terms of the Alpha Factor (αH) and the Four-Wave
Mixing (FWM). Besides, a Coherent Optical-Orthogonal Frequency Division Multiplexing
(CO-OFDM) simulation platform is used to confirm the good agreement between the measured
and the simulated Error Vector Magnitude (EVM) of a received signal amplified by the
studied SOA in an optical transmission link. In addition, the performance of the SOA on
the amplification of a 10.94 Gb/s QPSK CO-OFDM signal is numerically analyzed with
respect to the Amplified Spontaneous Emission (ASE) noise, the Alpha Factor, the output
saturation power of the SOA and the bit rate.
