Study on reflective semiconductor optical amplifier with segmented electrodes for self-seeded colorless WDM transmitter

摘要

Novel reflective semiconductor optical amplifier (RSOA) with segmented electrodes is proposed and demonstrated to simultaneously enhance the modulation canceling effect and extend the bandwidth for colorless self-seeded WDM transmitter applications. Optimal bias condition to each section is derived by a numerical model based on modified rate equations. The numerical predictions are confirmed by self-seeded experiments at a bitrate up to 10 Gb/s.
