Activating high-power parametric oscillation in photonic-crystal resonators
Grant M. Brodnik, Lindell M. Williams, Haixin Liu +4
By engineering the mode spectrum of a Kerr microresonator, we selectively activate nonlinear phase matching amongst broadband parametric gain. At threshold, optical parametric osci…
