少模光纤放大器
This few mode fiber Erbium doped amplifier has been developed within the MODE-GAP project. The amplifier covers C-band and is available in 3-mode (LP01, LP11a, LP11b) and 6-mode (LP01, LP11a, LP11b, LP21a, LP21b, LP02) options. Low noise figure and high gain is achievable across the full set of modes. The differential modal gain is low and flat across the wavelength range. Number of required pump ports can be defined by the user to provide individual mode group control.
