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…
Microwave-to-optical conversion using lithium niobate thin-film acoustic resonators
Linbo Shao, Mengjie Yu, Smarak Maity +8
We demonstrate conversion of up to 4.5 GHz-frequency microwaves to 1500 nm-wavelength light using optomechanical interactions on suspended thin-film lithium niobate. Our method uti…
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…
Coherent two-octave-spanning supercontinuum generation in lithium-niobate waveguides
Mengjie Yu, Boris Desiatov, Yoshitomo Okawachi +2
We demonstrate coherent supercontinuum generation (SCG) in a monolithically integrated lithium-niobate waveguide, under the presence of second- and third-order nonlinear effects. W…
