摘要：
The generation of amplified spontaneous emission (ASE) in erbium-doped fiber amplifiers is characterized. A theoretical model leading to closed-form analytical expressions for the backward and forward ASE power spectra is developed for the unsaturated gain regime. The results are found to be in close agreement with the measured experimental data. Such closed-form expressions are useful to model ASE noise in low-gain, distributed fiber amplifiers.
