Abstract :
A novel scheme, for the wired and wireless gigabit data transmission in optical access network, is proposed and experimentally demonstrated by using dual parallel injection locked Fabry-Perot laser diodes. In the proposed method, it was able to achieve both the optical carrier suppressed signals with high suppression ratio and high transmission performance for both baseband and 60-GHz signal by injection locking of each sideband and direct modulation of the Fabry-Perot laser diodes, respectively. Using the remodulation technique based on reflective semiconductor optical amplifier, it was possible to accomplish bidirectional 1.25 Gbps 20-km transmission (BER < 10-9) with the receiver sensitivity lower than - 20 dBm.
