Exploiting Ultralow Loss Multimode Waveguides for Broadband Frequency Combs
Xingchen Ji, Jae K. Jang, Utsav D. Dave +4
Low propagation loss in high confinement waveguides is critical for chip-based nonlinear photonics applications. Sophisticated fabrication processes which yield sub-nm roughness ar…
Observation of Arnold Tongues in Coupled Soliton Kerr Frequency Combs
Jae K. Jang, Xingchen Ji, Chaitanya Joshi +3
We demonstrate various regimes of synchronization in systems of two coupled cavity soliton-based Kerr frequency combs. We show sub-harmonic, harmonic and harmonic-ratio synchroniza…
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.…
On-chip dual comb source for spectroscopy
Avik Dutt, Chaitanya Joshi, Xingchen Ji +5
Dual-comb spectroscopy is a powerful technique for real-time, broadband optical sampling of molecular spectra which requires no moving components. Recent developments with microres…
