New method of gain and noise factor determination of an erbium-doped fiber optical amplifier by electrical noise measurements

摘要

Abstract: This communication deals with optical noise measurements of an erbium-doped fiber amplifier with input signal. We are able to determine the net gain and the noise factor from only these low frequency electrical noise measurements and new simple relations. It is presented as alternative to optical analyzer measurements and it has no limitation for high input signals. !4
