Weiqiang Xie, Peter Verheyen, Marianna Pantouvaki +2
Photonic crystal (PhC) nanocavities have demonstrated unique capabilities in terms of light confinement and manipulation. As such, they are becoming attractive for the design of no…
Ultrahigh-Q AlGaAs-on-insulator microresonators for integrated nonlinear photonics
Weiqiang Xie, Lin Chang, Haowen Shu +4
Aluminum gallium arsenide (AlGaAs) and related III-V semiconductors have excellent optoelectronic properties. They also possess strong material nonlinearity as well as high refract…
Dissipative Kerr Solitons in a III-V Microresonator
Gregory Moille, Lin Chang, Weiqiang Xie +5
We demonstrate stable microresonator Kerr soliton frequency combs in a III-V platform (AlGaAs on SiO) through quenching of thermorefractive effects by cryogenic cooling to temp…
Integrated turnkey soliton microcombs operated at CMOS frequencies
Boqiang Shen, Lin Chang, Junqiu Liu +14
While soliton microcombs offer the potential for integration of powerful frequency metrology and precision spectroscopy systems, their operation requires complex startup and feedba…
