Perfect soliton crystals in optical microresonators

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Martin Hubert Peter Pfeiffer, Hairun Guo, Wenle Weng

We demonstrate the existence of perfect soliton crystal states and develop the deterministic procedure for their excitation in Si3N4 microresonators. We show that despite exceptional symmetrical properties, their behavior is strongly linked to the chaotic ...

Coupling Ideality of Integrated Silicon Nitride Microresonators for Nonlinear Photonics

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Martin Hubert Peter Pfeiffer, Hairun Guo, Arne Kordts, Victor Brasch

Integrated microresonators are essential building blocks of linear and nonlinear photonic devices. Here we show that the performance of high-Q silicon nitride microresonators for nonlinear photonics strongly depends on the ideality of their coupler design. ...

Orthogonally polarized frequency comb generation from a Kerr comb via cross-phase modulation

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts

We experimentally demonstrate that a single microresonator can emit two orthogonally polarized individually coherent combs: (i) a strong polarized soliton comb and (ii) an orthogonally polarized continuous wave seeded weaker comb, generated from the first ...
