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…
Ultrabroadband Milliwatt-Level Resonant Frequency Doubling on a Chip
Marco Clementi, Luca Zatti, Ji Zhou +2
Microresonators are powerful tools to enhance the efficiency of second-order nonlinear optical processes, such as second-harmonic generation, which can coherently bridge octave-spa…
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…
