Emulating the local Kuramoto model with an injection-locked photonic crystal laser array
Naotomo Takemura, Kenta Takata, Masato Takiguchi +1
The Kuramoto model is a mathematical model for describing the collective synchronization phenomena of coupled oscillators. We theoretically demonstrate that an array of coupled pho…

Observing exceptional point degeneracy of radiation with electrically pumped photonic crystal coupled-nanocavity lasers
Kenta Takata, Kengo Nozaki, Eiichi Kuramochi +6
Controlling gain and loss of coupled optical cavities can induce non-Hermitian degeneracies of eigenstates, called exceptional points (EPs). Various unconventional phenomena around…
