Competition between Raman and Kerr effects in microresonator comb generation
Yoshitomo Okawachi, Mengjie Yu, Vivek Venkataraman +5
We investigate the effects of Raman and Kerr gain in crystalline microresonators and determine the conditions required to generate modelocked frequency combs. We show theoretically…
Low-Loss Silicon Platform for Broadband Mid-Infrared Photonics
Steven A. Miller, Mengjie Yu, Xingchen Ji +4
Broadband mid-infrared (mid-IR) spectroscopy applications could greatly benefit from today's well-developed, highly scalable silicon photonics technology; however, this platform la…
Modelocked mid-infrared frequency combs in a silicon microresonator
Mengjie Yu, Yoshitomo Okawachi, Austin G. Griffith +2
Mid-infrared (mid-IR) frequency combs have broad applications in molecular spectroscopy and chemical/biological sensing. Recently developed microresonator-based combs in this wavel…
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…
