Abstract

A pump and probe experiment is described which allows to study input coupling efficiency of a CdS grating on top of a linear glass waveguide as a function of input power for wavelengths shorter than CdS band gap wavelength. A monotonous decrease of coupling efficiency is found by increasing the pump power. Reference is made also to results obtained for wavelengths larger than the band gap wavelength.
