Soliton Crystals in Kerr Microresonator Frequency Combs
We explore ordered soliton ensembles in Kerr microresonators. These soliton crystals are stabilized through collective soliton interactions mediated by defects in resonator mode structure, and require only adiabatic tuning of the pump for generation. OCIS codes: (190.5530) Pulse propagation and temporal solitons; (140.3945) Microcavities Dissipative Kerr-cavity solitons are a promising candidat...
متن کاملCoherent terabit communications with microresonator Kerr frequency combs
Optical frequency combs have the potential to revolutionize terabit communications1. Generation of Kerr combs in nonlinear microresonators2 represents a particularly promising option3 enabling line spacings of tens of GHz. However, such combs may exhibit strong phase noise4-6, which has made high-speed data transmission impossible up to now. Here we demonstrate that systematic adjustment of pum...
متن کاملOn phase locking phenomena in Kerr combs
Based on a modal description of the evolution Kerr combs in a whispering-gallery mode resonator, we numerically investigate the phase behavior of the different spectral lines of the spectrum. We show that a stable phase relation exist between adjacent modes in primary combs. This result is of great interest for metrological applications were one phase noise is an issue. For high input power how...
متن کاملErratum: Closed-form solutions and scaling laws for Kerr frequency combs
A single closed-form analytical solution of the driven nonlinear Schrödinger equation is developed, reproducing a large class of the behaviors in Kerr-comb systems, including bright-solitons, dark-solitons, and a large class of periodic wavetrains. From this analytical framework, a Kerr-comb area theorem and a pump-detuning relation are developed, providing new insights into soliton- and wavetr...
متن کاملThermal tuning of Kerr frequency combs in silicon nitride microring resonators.
Microresonator based Kerr frequency comb generation has many attractive features, including ultrabroad spectra, chip-level integration, and low power consumption. Achieving precise tuning control over the comb frequencies will be important for a number of practical applications, but has been little explored for microresonator combs. In this paper, we characterize the thermal tuning of a coheren...
