Abstract
Second-harmonic generation exploiting evanescent field interaction has been investigated for a planar dielectric waveguide covered with a thin organic layer. The coherent nature of the frequency-doubling process in such a structure was studied experimentally by systematic ablation of the nonlinear film in an in situ setup. An increase in the conversion efficiency by two orders of magnitude has been observed for a nonoptimized second-order susceptibility of the coverage layer
