Abstract
Stabilization and control of coupled-cavity lasers are considered. Constant output power plots on the I1 vs I2 plane determine optimum dc bias points and how the rf modulation should be applied. A double feedback-loop control circuit provides stable, single-mode operation over wide ranges of temperature and power under modulation. Experiments demonstrate ≥24 dB of spurious mode suppression under almost complete on/off high-speed modulation over >15 °C.Keywords
