The effect of structural inhomogeneities in multi-quantum-well lasers caused by composition and well width fluctuations on the line-shape and gain of the lasers is discussed based on gaussian and uniform distribution models. Quantitative results of wide applicability are deduced. The results show that the structural inhomogeneities will reduce the gain and broaden the lineshape.
