Abstract
The theoretical basis for the noise figure of optical amplifiers is reviewed, and a consistent approach to determining the noise figure of cascaded components is developed. It is shown that when the noise figure is defined in terms of the input and output signal-to-noise ratios, the formulation provides a consistent theoretical formulation for measurement techniques using optical and optoelectronic measurement methods. The paper concludes with a review of measurement techniques for characterization of the noise figure.
