Performance analysis of a directly modulated semiconductor optical amplifiers using non‐return‐to‐zero, duobinary and quaternary pulse amplitude modulation signalling
ABSTRACT Numerical investigation was done for the response of two semiconductor optical amplifiers (SOA) to direct modulation using three of the most commonly employed intensity modulation formats: non‐return‐to‐zero (NRZ), duobinary (DB) and quaternary pulse amplitude modulation (PAM‐4). It was sho...
