Higher Order Mode Suppression in high-Q Anomalous Dispersion SiN Microresonators for Temporal Dissipative Kerr Soliton Formation

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Hairun Guo, Arne Kordts, Victor Brasch

Frequency comb generation based on dissipative Kerr solitons (DKS) in microresonators is important for many applications. We show higher order mode suppression in silicon nitride microresonators, that reduces avoided modal crossing to enable DKS generation ...

Widely Tunable Mid-IR Femtosecond Resonant Radiation Induced by Self-defocusing Solitons in a Quadratic Nonlinear Medium

Hairun Guo

We experimentally observe widely tunable mid-IR femtosecond pulses by resonant radiation, generated by direct three-wave-mixing from a soliton in PPLN. The poling pitch gives a parametrically tunable resonant radiation, a feature absent in Kerr media. ...

Dynamics of soliton crystals in optical microresonators

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

Dissipative Kerr solitons in optical microresonators combine nonlinear optical physics with photonic-integrated technologies. They are promising for a number of applications ranging from optical coherent communications to astrophysical spectrometer calibra ...

A chip-based silicon nitride platform for mid-infrared nonlinear photonics

Tobias Kippenberg, Camille Sophie Brès, Martin Hubert Peter Pfeiffer, Hairun Guo, Davide Grassani, Michail Zervas, Adrien Billat

We developed a chip-based silicon nitride platform with thick waveguides (> 2 mm) that overcomes the usual fabrication limitation. We demonstrate both microresonator frequency comb generation at 2:5 mm and supercontinuum generation extending beyond 4:0 mm ...

Universal Dynamics and Controlled Switching of Dissipative Kerr Solitons in Optical Microresonators

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Hairun Guo, Erwan Guillaume Albert Lucas, Arne Kordts, Victor Brasch

We discover a novel mechanism allowing for successive reduction of the number of dissipative Kerr solitons in optical microresonators. It is demonstrated that multiple and single soliton state can be deterministically accessed. ...

Efficient mid-infrared dispersive wave generation in dispersion-engineered Si3N4 waveguides pumped at 2 μm

Tobias Kippenberg, Camille Sophie Brès, Hairun Guo, Davide Grassani, Eirini Tagkoudi

We demonstrate efficient generation of mid-infrared dispersive wave at 3.5 m in a Si3N4 waveguide pumped by a 2090nm femtosecond mode-locked fiber laser. The 8% maximum efficiency allows for a milliwatt-level average power mid-infrared pulse. ...
