Characterizing pump line phase offset of a single-soliton Kerr comb by dual comb interferometry
Ziyun Kong, Chengying Bao, Oscar E. Sandoval +5
We experimentally demonstrate phase retrieval of a single-soliton Kerr comb using electric field cross-correlation implemented via dual-comb interferometry. The phase profile of th…
Thermo-Optical Chaos and Direct Soliton Generation in Microresonators
Chengying Bao, Yi Xuan, Jose A. Jaramillo-Villegas +2
We investigate, numerically and experimentally, the effect of thermo-optical (TO) chaos on direct soliton generation (DSG) in microresonators. When the pump laser is scanned from b…
Soliton repetition rate in a silicon-nitride microresonator
Chengying Bao, Yi Xuan, Cong Wang +4
The repetition rate of a Kerr comb comprising a single soliton in an anomalous dispersion silicon nitride microcavity is measured as a function of pump frequency tuning. The contri…
Frequency Comb Generation in 300 nm Thick SiN Concentric-Racetrack-Resonators: Overcoming the Material Dispersion Limit
Sangsik Kim, Kyunghun Han, Cong Wang +7
Kerr nonlinearity based frequency combs and solitons have been generated from on-chip optical microresonators with high quality factors and global or local anomalous dispersion. Ho…
Second-harmonic assisted four-wave mixing in chip-based microresonator frequency comb generation
Xiaoxiao Xue, François Leo, Yi Xuan +6
Simultaneous Kerr comb formation and second-harmonic generation with on-chip microresonators can greatly facilitate comb self-referencing for optical clocks and frequency metrology…
Observation of Fermi-Pasta-Ulam Recurrence Induced by Breather Solitons in an Optical Microresonator
Chengying Bao, Jose A. Jaramillo-Villegas, Yi Xuan +3
We present, experimentally and numerically, the observation of Fermi-Pasta-Ulam recurrence induced by breather solitons in a high-Q SiN microresonator. Breather solitons can be exc…
Intracavity characterization of micro-comb generation in the single-soliton regime
Pei-Hsun Wang, Jose A. Jaramillo-Villegas, Yi Xuan +5
Soliton formation in on-chip micro-comb generation balances cavity dispersion and nonlinearity and allows coherent, low-noise comb operation. We study the intracavity waveform of a…
Deterministic single soliton generation and compression in microring resonators avoiding the chaotic region
Jose A. Jaramillo-Villegas, Xiaoxiao Xue, Pei-Hsun Wang +2
A path within the parameter space of detuning and pump power is demonstrated in order to obtain a single cavity soliton (CS) with certainty in SiN microring resonators in the anoma…
