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…

Modeling of quasi-phase-matched cavity enhanced second harmonic generation

C. Mas Arabí, P. Parra-Rivas, C. Ciret +2

We propose a mean-field model to describe second harmonic generation in a resonator made of a material with zincblende crystalline structure. The model is obtained through an avera…

Four-wave mixing and enhanced analogue Hawking effect in a nonlinear optical waveguide

Scott Robertson, Charles Ciret, Serge Massar +2

We study in detail the scattering of light on a soliton propagating in a waveguide which has been proposed as an experimental system in which one could observe the analogue Hawking…
