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…
Broadband Ultrahigh-Resolution chip-scale Scanning Soliton Dual-Comb Spectroscopy
Tong Lin, Avik Dutt, Chaitanya Joshi +5
We present a chip-scale scanning dual-comb spectroscopy (SDCS) approach for broadband ultrahigh-resolution spectral acquisition. SDCS uses Si3N4 microring resonators that generate…
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.…
Gas-phase microresonator-based comb spectroscopy without an external pump laser
Mengjie Yu, Yoshitomo Okawachi, Chaitanya Joshi +3
We present a novel approach to realize microresonator-comb-based high resolution spectroscopy that combines a fiber-laser cavity with a microresonator. Although the spectral resolu…
