The efficiencies and output power of Er-doped superfluorescent fibre sources of three major configurations are compared when pumped near 980 nm and operated in their optimal either pump-power independent, or insensitive mean wavelength regions for the first time. It is shown the double-pass backward source has a better performance than the others.
