Abstract :
We identify key parameters that control the low-frequency damping commonly observed in optical injection-locked lasers. We demonstrate, experimentally and theoretically, that by biasing the slave laser at higher current, the impact of this damping can be eliminated. A record-high 80-GHz intrinsic 3-dB frequency is achieved.
