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…
Fabrication-tolerant frequency conversion in thin film lithium niobate waveguide with layer-poled modal phase matching
O. Hefti, J. -E. Tremblay, A. Volpini +11
Thanks to its high quadratic nonlinear susceptibilty and low propagation losses, thin film lithium niobate (TFLN) on insulator is an ideal platform for laser frequency conversion a…
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…
Ultrabroadband tunable difference frequency generation in standardized thin-film lithium niobate platform
Yesim Koyaz, Christian Lafforgue, Homa Zarebidaki +4
Thin-film lithium niobate (TFLN) on insulator is a promising platform for nonlinear photonic integrated circuits (PICs) due to its strong light confinement, high second-order nonli…
Monolithic silicon nitride electro-optic modulator enabled by optically-assisted poling
Christian Lafforgue, Boris Zabelich, Camille-Sophie Brès
Electro-optic (EO) modulation is a key functionality to have on-chip. However, achieving a notable linear EO effect in stoichiometric silicon nitride has been a persistent challeng…
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…
