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…

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…

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…
Physical origin of higher-order soliton fission in nanophotonic semiconductor waveguides
Charles Ciret, Simon-Pierre Gorza, Chad Husko +3
Supercontinuum generation in Kerr media has become a staple of nonlinear optics. It has been celebrated for advancing the understanding of soliton propagation as well as its many a…

By means of the ultrafast optical Kerr effect method coupled to optical heterodyne detection (OHD-OKE), we characterize the third order nonlinear response of graphene at telecom wa…
Scattering of a cross-polarized linear wave by a soliton at an optical event horizon in a birefringent nanophotonic waveguide
Charles Ciret, Simon-Pierre Gorza
The scattering of a linear wave on an optical event horizon, induced by a cross polarized soliton, is experimentally and numerically investigated in integrated structures. The expe…
