Twincore erbium-doped fibre amplifier with passive spectral gain equalisation
Automatic spectral gain equalisation is demonstrated using controlled spatial hole-burning in an erbium doped twincore fibre. Gain equalisation rates up to 0.11dB difference between input signal levels are demonstrated and should increase the useful bandwidth of cascaded amplifiers.
