利用自发辐射光谱的实验测量，我们已经确定了决定激光二极管的外部差分注入效率的组件。我们已经表明，即使来自n= 1个过渡引脚的发射处于阈值，也存在来自条带效率/spl eta//sub s/sup d/和注入效率/spl eta//sub i/sup d/两者的对高于阈值的/spl eta//sub o/sup d/的贡献，后者是由于阱外部没有钉扎。
Using experimental measurements of spontaneous emission spectra, we have identified the components which determine the external differential injection efficiency of laser diodes. We have shown that, even though the emission from the n=l transition pins at threshold, there are contributions to /spl eta//sub o//sup d/ above threshold from both the stripe efficiency /spl eta//sub s//sup d/ and the injection efficiency /spl eta//sub i//sup d/, the latter being due to the absence of pinning outside the well.
