摘要：

We show a thermally stable self -injection DFB laser lock to a microring resonator system, increasing the range of temperature for which a laser stays within 100 MHz of the target frequency by a factor of 100. By including amplification in the feedback loop, the per -laser power dedicated to this locking was reduced. We further added a 2.2 km fiber spool to explore the remote locking performance of the system. (c) 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
