To investigate the cascade process, we study two sets of mid- infrared InAs/GaInSb/AlSb multiple quantum well electroluminescent devices. Each set has nominally the same device parameters, differing only by the number of periods. We find, as expected, that for the same driving current the larger the device period the more intense is the emission. We also find that the scaling is far from ideal. We correlate the deviation of the exact scaling with the variation of the wafer-to-wafer structural quality.
