Counter-rotating cavity solitons in a silicon nitride microresonator
Chaitanya Joshi, Alexander Klenner, Yoshitomo Okawachi +5
We demonstrate the generation of counter-rotating cavity solitons in a silicon nitride microresonator using a fixed, single-frequency laser. We demonstrate a dual 3-soliton state w…
Coherent, directional supercontinuum via cascaded dispersive wave generation
Yoshitomo Okawachi, Mengjie Yu, Jaime Cardenas +3
We demonstrate a novel approach to producing coherent, directional supercontinuum via cascaded dispersive wave generation. By pumping in the normal group-velocity dispersion regime…
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…
