Determination of the noise figure of erbium-doped fibre amplifiers using the photon statistic master equation

摘要

The photon statistic master equation is used to calculate the photon probability distribution at the output of optical components. The result is used to obtain the noise figure of an ideal optical attenuator and an ideal optical amplifier. In combination with the measured signal-to-noise ratio at the output of a real optical amplifier, the noise figure of this amplifier is calculated.
