Note (General): 本研究では，外界との結合による散逸や利得のある光微小共振器系に注目し，例外点(exceptional point, EP)と呼ばれる特異な点近傍における光学・発振現象を理論的に調べた．その結果，（1）EP近傍で動作させたリング型微小共振器は回転摂動に対して従来の100倍以上大きな周波数シフトを与えること，（2）周波数シフトだけでなく入力信号に対する応答強度も劇的に増幅できること，（3）アクティブ共振器では，量子的揺らぎに敏感に反応してレーザ発振線幅が大幅に増大することを解明した.
We numerically and theoretically studied optical phenomena in microcavities operating near exceptional points (EPs). The main results are as follows: (1) frequency splitting due to rotation can be enhanced in a ring resonator with a complex periodic structure. This opens a novel way of sensitivity enhancement toward on-chip optical gyroscopes.(2) The frequency response function near an EP was derived. It was shown that the response can be enhanced in proportional to the fourth power of the loss rate of an optical cavity. (3) A novel laser operating at an EP was proposed. It was also shown that the laser linewidth can greatly be broadened, compared to normal lasers that do not operate an EP, suggesting that the laser coherence can be changed by using an EP.
