Abstract: A dummy light module includes a dual semiconductor optical amplifier (SOA) light source configured to emit two substantially identical light emissions. The two light emissions include a first light emission and a second light emission, both having a first polarization. The dummy light module further includes a polarization rotator configured to rotate the second light emission to a second polarization, and a polarization beam combiner configured to generate dummy light by combining the first light emission with the first polarization and the second light emission with the second polarization.
