摘要：

The validity of the usual Marcuse-Gaussian approximation for fiber modes is discussed in the context of doped fiber amplifiers and an alternative spot-size polynomial is proposed: [GRAPHICS] The polynomial's use is illustrated by extending the range of a simple Gaussian-based, numerical model of an erbium-doped fiber amplifier. Excellent agreement with a ''real field'' based model is demonstrated for practical fiber V-values.
