Fourth-harmonic UV light generation in integrated silicon nitride microresonators

Alekhya Ghosh, Arghadeep Pal, Haochen Yan +6

Integrated silicon nitride (Si3N4) resonators have emerged as a leading platform for nonlinear photonics, yet generating light at wavelength in the ultraviolet (UV) has remained el…

Hybridized-band parametric oscillations in coupled Kerr microresonators

Luca O. Trinchão, Luiz Peres, Eduardo S. Gonçalves +6

Coupled resonators form band-like optical states that support rich nonlinearities beyond what is possible in single resonators. In these systems, four-wave mixing mediates interban…

Mapping Nonlinear Mode Interactions in Coupled Kerr Resonators

Luca O. Trinchão, Luiz Peres, Eduardo S. Gonçalves +6

We present a method for resolving spatial mode overlaps in coupled microresonators based on Kerr and thermal cross-phase modulation. Through a pump-probe setup, we measure experime…
