Exceptional point proximity-driven mode-locking in coupled microresonators
Riku Imamura, Shun Fujii, Ayata Nakashima +1
We show theoretically and numerically that mode-locking is feasible with a coupled-cavity system with gain and loss, notably, without any natural saturable absorber. We highlight t…

Mechanically actuated Kerr soliton microcombs
Shun Fujii, Koshiro Wada, Soma Kogure +1
Mode-locked ultrashort pulse sources with a repetition rate of up to several tens of gigahertz greatly facilitate versatile photonic applications such as frequency synthesis, metro…
