摘要:
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.
