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…
Breaking the Loss Limitation of On-chip High-confinement Resonators
Xingchen Ji, Felippe A. S. Barbosa, Samantha P. Roberts +6
On-chip optical resonators have the promise of revolutionizing numerous fields including metrology and sensing; however, their optical losses have always lagged behind their larger…
Raman-assisted coherent, mid-infrared frequency combs in silicon microresonators
Austin G. Griffith, Mengjie Yu, Yoshitomo Okawachi +4
We demonstrate the first low-noise mid-IR frequency comb source using a silicon microresonator. Our observation of strong Raman scattering lines in the generated comb suggests that…
