Nonlinear Dynamics of Coupled-Resonator Kerr-Combs
Swarnava Sanyal, Yoshitomo Okawachi, Yun Zhao +4
The nonlinear interaction of a microresonator pumped by a laser has revealed complex dynamics including soliton formation and chaos. Initial studies of coupled-resonator systems re…
Synchronization of non-solitonic Kerr combs
Bok Young Kim, Jae K. Jang, Yoshitomo Okawachi +3
Synchronization is a ubiquitous phenomenon in nature that manifests as the spectral or temporal locking of coupled nonlinear oscillators. In the field of photonics, synchronization…
On-chip self-referencing using integrated lithium niobate waveguides
Yoshitomo Okawachi, Mengjie Yu, Boris Desiatov +4
The measurement and stabilization of the carrier-envelope offset frequency via self-referencing is paramount for optical frequency comb generation which has revo…
Nanophotonic spin-glass for realization of a coherent Ising machine
Yoshitomo Okawachi, Mengjie Yu, Jae K. Jang +5
The need for solving optimization problems is prevalent in a wide range of physical applications, including neuroscience, network design, biological systems, socio-economics, and c…
Turn-key, high-efficiency Kerr comb source
Bok Young Kim, Yoshitomo Okawachi, Jae K. Jang +6
We demonstrate an approach for automated Kerr comb generation in the normal group-velocity dispersion (GVD) regime. Using a coupled-ring geometry in silicon nitride, we precisely c…
Visible nonlinear photonics via high-order-mode dispersion engineering
Yun Zhao, Xingchen Ji, Bok Young Kim +11
Over the past decade, remarkable advances have been realized in chip-based nonlinear photonic devices for classical and quantum applications in the near- and mid-infrared regimes.…
