Semiconductor Laser Linewidth Theory Revisited [PDF]
Applied Sciences, 2021 More and more applications require semiconductor lasers distinguished not only by large modulation bandwidths or high output powers, but also by small spectral linewidths. The theoretical understanding of the root causes limiting the linewidth is therefore of great practical relevance.
