Abstract

This study presents a method to improve the efficiency of semiconductor optical amplifier (SOA)-based optical network units (ONUs). The method is based on the combination of remote seeding and self-seeding schemes, which is referred to as the feedback seeding (FBS) scheme. In the proposed method, a centralised laser source provides a coherent light wave at the optical line terminal. At the ONU, a fibre Bragg grating is positioned to reflect a small percentage of the SOA output to increase seeding power. Consequently, the instauration issue is overcome by achieving coherent light power and a higher data rate. A colourless FBS-ONU is also demonstrated in this research. Simulation results demonstrate that the proposed FBS scheme can operate sufficiently with a low seeding power from the central office. In the remote seeding scheme, sensitivity increases as seeding power increases. On the other hand, in the FBS scheme, sensitivity is high and constant at seeding power values of -30 dBm and above. In this study, sensitivity is -23 dBm. The results show that the proposed scheme provides significant improvement in bit error rate performance and optical signal to noise ratio.
