Low-cost WDM-PON source amplification scheme using bidirectional semiconductor linear optical amplifier

A cost-effective and compact WDM-PON source amplification scheme with bidirectional semiconductor optical amplifier is firstly demonstrated. A linear optical amplifier is used as a bidirectional amplifier to obtain the gain clamping of downstream channels and suppress the cross-gain modulation between upstream and downstream channels. We show the experimental results including the transient responses with a dynamic wavelength channel add/drop in WDM-PON.
