From Microresonator to Packaged Microcomb System: Fiber-Coupled Module and System Integration
Abstract
We demonstrate a compact and robust soliton microcomb source designed for field-deployable operation. A directly fiber-coupled SiN microresonator was integrated with precise thermal control into a palm-sized module, reducing the footprint and volume by 16- and 81-fold, respectively. The module, together with the laser sources and optical amplifiers required for microcomb generation, was further integrated into a 19-inch rack-mounted enclosure, achieving system-level footprint and volume reductions of 2.3- and 3.7-fold, respectively. The packaged system achieved a 90% manual startup success rate and maintained continuous soliton operation for 18.8 days, while remaining operational under substantial temperature variations. A state-based automated startup scheme using discrete microcomb-state evaluation achieved single-soliton generation without manual intervention with success rates of 50% within 2 min and 60% within 3 min. Moreover, automated soliton initiation and sustained operation were demonstrated while the packaged microresonator module was directly subjected to random mechanical vibration. These results provide a practical platform for compact, robust, and field-deployable microcomb sources.
