Theory of -microresonator-based frequency conversion
Yun Zhao, Jae K. Jang, Yoshitomo Okawachi +1
Microresonator-based platforms with nonlinearities have the potential to perform frequency conversion at high efficiencies and ultralow powers with small footprints. The…
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…
Frequency-Domain Quantum Interference with Correlated Photons from an Integrated Microresonator
Chaitali Joshi, Alessandro Farsi, Avik Dutt +6
Frequency encoding of quantum information together with fiber and integrated photonic technologies can significantly reduce the complexity and resource requirements for realizing a…
Near-degenerate quadrature-squeezed vacuum generation on a silicon-nitride chip
Yun Zhao, Yoshitomo Okawachi, Jae K. Jang +3
Squeezed states are a primary resource for continuous-variable (CV) quantum information processing. To implement CV protocols in a scalable and robust way, it is desirable to gener…
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.…
