Dynamics of Soliton Microcomb Self-Injection Locking in a Silicon Nitride Microresonator

Tobias Kippenberg, Junqiu Liu, Andrey Voloshin

We demonstrate a chip-scale 30 GHz single soliton microcomb based on DFB laser locked to a Si3N4 microresonator. We propose novel theoretical and experimental approaches to explain dynamics of self-injection locking, modified by Kerr nonlinearity. (c) 2020 ...

Thermo-optic tuning of spectral broadening in a nonlinear Ultra-Silicon-Rich Nitride grating

Jae-Woo Choi

Temperature tuning of spectral broadening induced by a nonlinear grating is experimentally demonstrated. The bandwidth is observed to decrease as temperature increases, corresponding to a red-shift in the high dispersion region of the Bragg grating. ...

Physics of Dissipative Kerr Solitons in Optical Microresonators and Application to Frequency Synthesis

Erwan Guillaume Albert Lucas

Optical-frequency combs, that is spectra of equidistant coherent optical lines, have revolutionized the precision measurements of time and frequency. In 2007 a new method to generate optical frequency combs was discovered. In contrast to conventional gener ...

Orthogonally polarized frequency comb generation from a Kerr comb via cross-phase modulation

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts

We experimentally demonstrate that a single microresonator can emit two orthogonally polarized individually coherent combs: (i) a strong polarized soliton comb and (ii) an orthogonally polarized continuous wave seeded weaker comb, generated from the first ...

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 ...
