With optical spectral marks equally spaced by a frequency in the microwave or the radio frequency domain, optical frequency combs have been used not only to synthesize optical frequencies from microwave references but also to generate ultralow-noise microw ...

Optical soliton molecules are bound states of solitons that arise from the balance between attractive and repulsive effects. Having been observed in systems ranging from optical fibres to mode-locked lasers, they provide insights into the fundamental inter ...

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) ...

We demonstrate piezoelectric actuators monolithically integrated on ultralow-loss Si3N4 waveguides. Varying the voltage applied on the actuator allows microresonator tuning, and to initiate, switch, stabilize and tightly phase lock the single soliton micro ...

Since their discovery microresonator-based frequency combs have drawn a lot of interest due to their compact form factor and potential for integration. We report on the recent progress regarding dissipative Kerr solitons generated from photonic chip-based ...

Using phase-modulation-induced potential gradient whose period is synchronized to a microwave opto-electronic oscillator, dissipative Kerr solitons generated in a crystalline optical microresonator are trapped by the soliton tweezing effect, exhibiting a s ...

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 ...

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 ...

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 ...

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 ...

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 ...

A dual-frequency-comb spectrometer and a method for spectroscopic investigation of a sample are described. The spectrometer includes first and second frequency comb devices for emitting laser pulses along first and second light paths, wherein the repetitio ...

We demonstrate broadband soliton-based resonant supercontinuum generation in a chip-based microresonator. We show that the soliton possesses an intrinsic ability to filter RF noise transfer from the input pulses, which can be further improved with asynchro ...

We demonstrate an architecture for massively parallel frequency-modulated continuous wave (FMCW) laser ranging (LiDAR) by transferring linear chirps of a single narrow linewidth laser onto all soliton comb teeth though generation of a dissipative Kerr soli ...

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 ...

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 ...

Stable and tunable integrated lasers are fundamental building blocks for applications from spectroscopy to imaging and communication. Here the authors present a narrow linewidth hybrid photonic integrated laser with low frequency noise and fast linear wave ...

We develop a dual-comb system based on a single crystalline microresonator by monochromatically pumping counter-propagating solitons in the same spatial mode with equal powers and unveil the role of soliton Cherenkov radiations interference in the process. ...
