Abstract :
The authors report, for the first time, measurements of signal spectral broadening caused by phase noise in an erbium-doped fibre amplifier. The spectral broadening was found to be less than 20 kHz. Thus it will not limit the performance of phase or frequency modulated coherent systems employing fibre amplifiers.
