Efficient Type II Second Harmonic Generation in an Indium Gallium Phosphide on insulator wire waveguide aligned with a crystallographic axis
Nicolas Poulvellarie, Carlos Mas Arabi, Charles Ciret +7
We theoretically and experimentally investigate type II second harmonic generation in III-V-on-insulator wire waveguides. We show that the propagation direction plays a crucial rol…
Full Vectorial Modeling of Second Harmonic Generation in III-V-on-insulator Nanowires
Charles Ciret, Koen Alexander, Nicolas Poulvellarie +5
We model second harmonic generation in subwavelength III-V-on-insulator waveguides. The large index contrast induces strong longitudinal electric field components that play an impo…
Second Harmonic Generation Enabled by Longitudinal Electric Field Components in Photonic Wire Waveguides
Nicolas Poulvellarie, Utsav Dave, Koen Alexander +10
We investigate type I second harmonic generation in III-V semiconductor wire waveguides aligned with a crystallographic axis. In this direction, because of the single nonzero tenso…
Highly Non-Degenerate Two-Photon Absorption in Silicon Wire Waveguides
Nicolas Poulvellarie, Charles Ciret, Bart Kuyken +2
Non-degenerate two-photon absorption (TPA) is investigated in a nanophotonic silicon waveguide in a configuration such that the dispersion of the nonlinear absorption and refractio…
