This cladding pumped few mode fiber Erbium doped
amplifier has been developed within the EU supported
MODE GAP project. The amplifier covers the C band
and is available in a 6 mode
(LP01, LP11a, LP11b, LP21a, LP21b, LP02)
configuration. Low noise figure and high gain are
achievable across the full set of modes. The
differential modal gain is low and flat across the full
optical C-band. A side pumping scheme was adapted
to realize a fully fiberized integrated SDM amplifier.
