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…
Nondegenerate Two-Photon Absorption in GaAs/AlGaAs Multiple Quantum Well Waveguides
Nicholas Cox, Junxiong Wei, Himansu Pattanaik +4
We present femtosecond pump-probe measurements of the nondegenerate (1960nm excitation and 1176--1326nm probe) two-photon absorption spectra of 8 nm GaAs/12nm Al$_{…
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…
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…
