Abstract Microcavities enable the generation of highly efficient microcombs, which find applications in various domains, such as high-precision metrology, sensing, and telecommunications. Such generally require precise control over spectral features free range, envelope, bandwidth. Most existing methods for customizing microcomb still rely on manual exploration a large parameter space, often lacking practicality versatility. In this work, we propose smart approach that employs genetic...
Mode-locking techniques have played a pivotal role in developing and advancing laser technology. Stable fiber-cavity configurations can generate trains of pulses spanning from MHz to GHz speeds, which are fundamental various applications micromachining, spectroscopy, communications. However, the generation exploitation multiple timescales single cavity configuration remain unexplored. Our work demonstrates designed control pulse nanosecond picosecond with broadband output low mode-locking...
