Abstract
We have systematically studied the well number dependence of the linew idth enhancement factor in strained quantum-well (QW) lasers and have demonstrated experimentally that the linewidth enhancement factor can be reduced from similar to 9.4 to similar to 2.0 by increasing the num ber of compressively strained QW's from 2 to 8. This behavior is prima rily due to an increase in the differential gain with the number of QW 's.
