导出了一个半对数表达式，它精确地近似了量子阱激光器的增益-电流曲线，对优化器件性能是有用的。推导使用计算曲线的曲线拟合和包括增益模型的积分的近似分析评估。导出的表达式用于解释所观察到的单量子阱和多量子阱激光器阈值电流的增加。
A semilogarithmic expression that accurately approximates gain‐current curves of quantum‐well lasers and is useful for optimization of device performance is derived. The derivation uses both a curve fitting of the calculated curves and approximate analytical evaluation of integrals that comprise the gain model. The derived expression is used to explain the observed increase in the threshold current of single‐ and multiple‐quantum‐well lasers.
