From order to chaos in a chip-scale Kerr parametric oscillator
Luca O. Trinchão, Juan Diego Mazo-Vásquez, Miguel Nienstedt +13
Integrated photonics has enabled a wide class of chip-scale light sources and quantum technologies. Within this field, microresonator-based degenerate optical parametric oscillator…
Vectorial engineering of second-harmonic generation in silicon-based waveguides integrated with 2D materials
Mohd Rehan, Nathalia B. Tomazio, Alisson R. Cadore +4
Integrating 2D materials onto on-chip photonic devices holds significant potential for nonlinear frequency conversion across various applications. The lack of inversion symmetry in…
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…
Color symmetry breaking in a nonlinear optical microcavity
Luca O. Trinchão, Alekhya Ghosh, Arghadeep Pal +8
Spontaneous symmetry breaking leads to diverse phenomena across the natural sciences, from the Higgs mechanism in particle physics to superconductors and collective animal behavior…
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…
