Parametric amplification in GaAs/AlOx waveguide
E. Guillotel, M. Ravaro, F. Ghiglieno, C. Langlois, C. Ricolleau et al.
We report the direct proof of parametric amplification in a semiconductor waveguide. Thanks to low propagation losses and high nonlinear efficiency, we amplified an input signal at 2 [mu]m in a selectively oxidized GaAs/AlAs multilayer waveguide through the down conversion of a pump at 1 [mu]m. Th ... [Appl. Phys. Lett. 94, 171110 (2009)] published Wed Apr 29, 2009.
