Stability regimes and high-frequency modulation of laser diodes with short external cavity

The results of a linear analysis of stationary generation stability for short external cavity laser diodes in a wide range of coupling coefficients, with the effect of external cavity mode beating being taken into account, are presented. Besides the coherence-collapse transition, high-frequency instability due to mode interaction is revealed and investigated. The results of linear theory are confirmed by computer simulations. They may be considered as guidelines for the design of high-speed laser diodes with integrated passive cavities.<
