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…
Raman lasing and soliton modelocking in lithium-niobate microresonators
Mengjie Yu, Yoshitomo Okawachi, Rebecca Cheng +4
The recent advancement in lithium niobate on insulator (LNOI) technology is revolutionizing the optoelectronic industry as devices of higher performance, lower power consumption, a…
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.…
Supercontinuum generation in angle-etched diamond waveguides
Amirhassan Shams-Ansari, Pawel Latawiec, Yoshitomo Okawachi +8
We experimentally demonstrate on-chip supercontinuum generation in the visible region in angle etched diamond waveguides. We measure an output spectrum spanning 670 nm to 920 nm in…
Chip-based frequency combs sources for optical coherence tomography
Xingchen Ji, Alexander Klenner, Xinwen Yao +4
The Optical coherence tomography (OCT) is a powerful interferometric imaging technique widely used in medical fields such as ophthalmology, cardiology and dermatology, for which fo…
