Nano-photonic Supercontinuum Based Mid-Infrared Dual-Comb Spectroscopy

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

We demonstrate an approach to dual-comb spectroscopy, based on dispersion engineered and ultra-broadband supercontinuum generation in photonic integrated nonlinear waveguides, and driven by low-noise fiber-laser combs. Both technologies arc statc-of-the-ar ...

Frequency Division Using a Soliton-Injected Semiconductor Gain-Switched Frequency Comb

Tobias Kippenberg, Junqiu Liu, Wenle Weng

By injecting a soliton microcomb into a semiconductor laser that is driven by a sinusoidal current at the subharmonic frequencies of the soliton rate, we demonstrate broadband gain-switched frequency comb generation and low-noise microwave synthesis. (C) 2 ...

Multistability-Enabled Complex Soliton Dynamics in a Bichromatically Driven Optical Microresonator

Tobias Kippenberg, Wenle Weng

We enter a bichromatically-pumped multistability regime in a microresonator to observe the emergence of complex dynamics of dissipative Kerr soliton interactions, including short-range soliton binding and periodic soliton collision. (C) 2020 The Author(s) ...

Nanophotonic supercontinuum based mid-infrared dual-comb spectroscopy

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

We demonstrate a broadband mid-infrared dual-comb spectroscopy for parallel gas-phase detection in the functional group region from 2800–3600 cm−1, using dispersion engineered silicon nitride dual-core waveguides which produce broadband, intensity-enhanced ...

Heteronuclear Soliton Molecules in Optical Microresonators

Tobias Kippenberg, Erwan Guillaume Albert Lucas, Wenle Weng, Tobias Herr

We enter the multi-stability regime of an optical microresonator to generate heteronuclear soliton molecules. Ultrafast electro-optical sampling reveals the bound structures of such soliton molecules, despite comprising solitons of dissimilar amplitudes, d ...

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 ...

Polychromatic Cherenkov Radiation Induced Group Velocity Symmetry Breaking in Counterpropagating Dissipative Kerr Solitons

Tobias Kippenberg, Erwan Guillaume Albert Lucas, Wenle Weng

High-order-dispersion-induced dispersive waves emitted by dissipative Kerr solitons are frequently observed in microresonator frequency comb generation. Also known as soliton Cherenkov radiation, this type of dispersive wave plays a critical role in comb s ...

Visible-near-middle infrared spanning supercontinuum generation in a silicon nitride (Si3N4) waveguide

Tobias Kippenberg, Junqiu Liu, Wenle Weng

We demonstrate the generation of a supercontinuum spanning more than 1.5 octaves over the 1.2-3.7 mu m range in a silicon nitride waveguide using sub-40-fs pulses at 2.35 mu m generated by a 75 MHz Kerr-lens mode-locked Cr:ZnS laser. (C) 2019 Optical Socie ...

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 ...
