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…
Supercontinuum generation assisted by dispersive waves trapping in dispersion-managed integrated silicon waveguides
Junxiong Wei, Charles Ciret, Maximilien Billet +3
Compact chip-scale comb sources are of significant interest for many practical applications. Here, we experimentally study the generation of supercontinuum (SC) in an axially varyi…
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…
