摘要

A classical phase-amplitude description of the optical field is proposed to discuss the optical amplifier noise generation. This description allows pointing out the contributions to output noise of the vacuum fluctuation input noise and of the intrinsic amplification and attenuation noises mechanisms. Comparison is done with the standard Amplified Spontaneous Emission (ASE) and associated beat noise approach. The model is applied to the theoretical noise figure discussion for distributed amplifiers, as a function of built in internal loss and values of the net gain achieved, and to the derivation of the equivalent lumped amplifier noise figure.
