Key Points

Phase noise of the microcomb was measured at -130 dBc/Hz at a 10 kHz offset, demonstrating excellent stability.
The all-fiber coupling technique promotes efficient self-injection locking in crystalline microcavities, enhancing performance.
Microcomb generation operates at a frequency of 25-GHz, making it suitable for various photonic applications.
The findings suggest that the all-fiber coupling could lead to advancements in high-precision measurement tools.

Implication

All-fiber coupling enhances phase noise performance in microcomb generation, indicating improved stability.

Abstract

We demonstrate a compact all-fiber coupling scheme for self-injection locked microcomb generation in ultra-high-Q crystalline microcavities. The phase noise of the free-run 25-GHz microcomb reaches -130 dBc/Hz at a 10 kHz offset.
