Backward-Wave Difference-Frequency Generation in Thin-Film Lithium Niobate
Yesim Koyaz, Ozan Yakar, Furkan Ayhan +3
Second-order nonlinear processes involving counter-propagating light generation have been explored for quantum applications and optical parametric oscillators. However, realizing t…
Reconfigurable Resonant Multimode Nonlinear Coupling for UV-to-infrared Frequency Generation
Samantha Sbarra, Ji Zhou, Boris Zabelich +6
On-chip coherent visible and near-infrared (NIR) light generation has broad applications in metrology, bio-sensing, and quantum information. High-Q microresonators are ideal candid…
Broadband spectral mapping of photo-induced second-harmonic generation in silicon nitride microresonators
Ji Zhou, Marco Clementi, Samantha Sbarra +2
By employing a pump-probe technique for enhanced spectral mapping of the dynamics in nonlinear frequency conversion, we demonstrate that photo-induced second-harmonic generation (S…
Integrated tunable green light source on silicon nitride
Gang Wang, Ozan Yakar, Xinru Ji +7
Integrated green light sources are essential for telecommunications and quantum applications, while the performance of current on-chip green light generation is still limited in po…
Self-organized spatiotemporal quasi-phase-matching in microresonators
Ji Zhou, Jianqi Hu, Marco Clementi +4
Quasi-phase-matching (QPM) is a widely adopted technique for mitigating stringent momentum conservation in nonlinear optical processes such as second-harmonic generation (SHG). It…
