This lecture covers the optimization of quantum well based laser diodes, including the determination of the optimum number of quantum wells to minimize threshold current density. It also delves into edge emitting laser diodes' beam properties, optical gain measurements using the variable stripe length and Hakki-Paoli methods, laser mode spacing, and the distributed feedback geometry for single longitudinal mode operation. The lecture concludes with the explanation of the Schawlow-Townes linewidth formula and its application to semiconductor laser diodes.
