Amplified RSOA Self-Tuning Laser for WDM PON Using Saturated SOA for Noise Reduction and Data Cancellation

we evaluated different km-long WDM PON laser sources based on amplified self-tuning solution. RIN reduction and data cancellation are demonstrated by using saturated SOA inside the cavity. The BER performance at 2.5Gb/s was enhanced with up to 50km cavity length.
