Dynamics of soliton crystals in optical microresonators

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

Perfect soliton crystals in optical microresonators

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

Photonic Integrated K-Band Microwave Oscillator Based on Silicon Nitride Soliton Microcomb

Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Maxim Karpov, Hairun Guo, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Guanhao Huang, Jijun He, Nils Johan Engelsen

Using photonic integrated silicon nitride microresonators of quality factor exceeding 15 million, we demonstrate 19-GHz-repetition-rate single soliton with 35 mW optical power, and characterize the phase noise of the repetition rate in the K-band microwave ...

Electrically Driven Ultra-compact Photonic Integrated Soliton Microcomb

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Hairun Guo, Erwan Guillaume Albert Lucas, John David Jost, Arslan Sajid Raja, Andrey Voloshin

We demonstrate a current-initiated soliton microcomb by injection-locking a multi-frequency laser diode to a chip-scale high-Q Si3N4 microresonator. This approach offers a pathway for integrated and ultra-compact microcomb source for high-volume applicatio ...

Spectral Purification of Microwave Signals with Disciplined Dissipative Kerr Solitons

Tobias Kippenberg, Hairun Guo, Erwan Guillaume Albert Lucas, Wenle Weng

Continuous-wave-driven Kerr nonlinear microresonators give rise to self-organization in terms of dissipative Kerr solitons, which constitute optical frequency combs that can be used to generate low-noise microwave signals. Here, by applying either amplitud ...

Electrically driven photonic integrated soliton microcomb

Tobias Kippenberg, Maxim Karpov, Junqiu Liu, Hairun Guo, John David Jost, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Andrey Voloshin

We demonstrate via self-injection locking an electrically driven soliton micro-comb by coupling a multi-frequency laser diode to a chip-scale high-Q Si3N4 microresonator. This approach offers a pathway for an integrated and ultra-compact microcomb source f ...

Gas spectroscopy using low threshold mid-infrared radiation generated in Si3N4 waveguides

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

We report trace-gas absorption spectroscopy based on the efficient generation of a 3.05μm dispersive wave in a Si3N4 waveguide pumped by a 2.09 μm femtosecond mode-locked fiber laser ...

Electrically pumped photonic integrated soliton microcomb

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Hairun Guo, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, John David Jost, Andrey Voloshin

Microcombs provide a path to broad-bandwidth integrated frequency combs with low power consumption, which are compatible with wafer-scale fabrication. Yet, electrically-driven, photonic chip-based microcombs are inhibited by the required high threshold pow ...

Nanophotonic Supercontinuum-Based Mid-Infrared Dual-Comb Spectroscopy

Luc Thévenaz, Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Hairun Guo, Wenle Weng, Wolfgang Hänsel

An optically stabilized dual-comb system at telecom wavelength is used to drive a mid-infrared spectroscopy for parallel gas-phase detection in the functional group region from 2800-3600 cm -1 . A coherent broadband intensity-enhanced spectrum in the mid-i ...
