| Outline of Final Research Achievements |
In this research, we proposed an all-fiber-based mode-filtering technique using a long-fiber-based fiber cavity to overcome the physical limitation of high-repetition rate Er-fiber based frequency comb. A high finesse fiber cavity and a high side-mode-suppression ratio of approximately 65 dB are achieved by introducing a ultra-low loss fiber splicing technique. The fiber cavity length is also stabilized such that the resonance frequency is locked to the comb mode by applying the Pound-Drever-Hall stabilization technique. The proposed stabilized all-fiber-based mode-filtering technique is expected to be an attractive choice for a variety of applications that require a high-repetition-rate frequency comb.

| Academic Significance and Societal Importance of the Research Achievements |
ギガヘルツ（GHz）以上の繰り返し周波数を有する、GHz光コムは、コムモードを直接利用できるため、天文応用・高精度マイクロ波発生・直接分光など、様々な応用がある。しかし、GHz光コムをレーザーから直接かつ安定に発生することは技術的に難しい。本研究では、環境変動に対して強い、繰り返し周波数100 MHz以下のファイバ型光コムを基に、全ファイバ型構成による、GHz光コムの安定な発生技術を開発した。全ファイバ型構成により、アライメントは不要であり、非常に簡便な構成でGHz光コムが得られた。
