Burst-off-level power reduction in λ-tunable transmitter using a reverse bias voltage controlled burst-mode booster SOA for 256-split WDM/TDM-PON

We propose a burst-off-level power reduction technique for a burst-mode booster SOA implemented λ-tunable transmitter. A large power reduction of 8.2 dB and a low crosstalk penalty of <;0.1 dB in 256-split WDM/TDM-PON are achieved.
