Outline of Research at the Start

次世代無線通信では100 GHz以上の高周波のミリ・THz波のキャリアが必要になる。しかし、既存のエレクトロニクス技術である周波数逓倍による手法では位相雑音の劣化が問題となる。本研究では、マイクロコムと呼ばれる集積可能なチップスケールの光周波数コムの低位相雑音化の研究を行い、マイクロコムをフォトディテクタに照射することで、マイクロコムのコムモード間隔(100 GHz - 1 THz)に対応した低位相雑音なミリ・THz波発生を行う。

Outline of Annual Research Achievements

去年度までに2波長自己遅延ヘテロダイン干渉計(two-wavelength delayed-self heterodyne interferometer: TWDI)を使って長尺ファイバーにマイクロコムを安定化することで、マイクロコムの繰り返し周波数の低位相雑化、ならびに低位相雑音THz波発生に成功した。しかし、低位相雑音と引き換えにシステムの複雑性が増加した。そこで、簡易的な方法としてAvoided Mode Crossing (AMX)を利用する手法を提案し、数値計算で原理実証を行った。提案手法では結合共振器系を使うことでAMXの位置と強さを調整する。さらに、実験による原理実証の準備として、結合共振器系における共鳴周波数の基本特性の評価と、結合共振器系からのマイクロコム発生を行った。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

マイクロコムの新規低雑音化手法を考案し、数値計算による原理実証に成功したため。

Strategy for Future Research Activity

AMXを利用する手法の実験的な原理実証を進める。具体的にはAMXが起きる共鳴周波数モードを変えることでマイクロコムの光スペクトルが変化し、それによりマイクロコムの位相雑音が低減かどうかを確認する。
