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…

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$_{…
