The thermal nonlinear response of a waveguide produced by sputtering a Corning 7059 glass film over a nonlinear substrate(Corning CS2-61) is studied with a pump-probe technique in a quasi-cw regime. The coupling efficiency is found to be a function of pump power and chopping frequency. The coupling zone is scanned with a probe beam to examine the spatial dependence of the coupling efficiency.

Abstract
The thermal nonlinear response of a waveguide produced by sputtering a Corning 7059 glass film over a nonlinear substrate(Corning CS2-61) is studied with a pump-probe technique in a quasi-cw regime. The coupling efficiency is found to be a function of pump power and chopping frequency. The coupling zone is scanned with a probe beam to examine the spatial dependence of the coupling efficiency.File allegati a questo prodotto
