Coherent kinks in high-power ridge waveguide laser diodes

Research output: Contribution to journalArticlepeer-review


Coherent coupling of lateral modes is suggested to explain the phenomena associated with beam-steering kinks, which appear in the L - I curves of many ridge waveguide lasers. The analysis that is presented explains quantitatively the previously reported experiments.
