Abstract

We have demonstrated experimentally the coupling between two thin-film waveguides with a sputter-etched grating as the phase-matching element. A maximum coupling efficiency of only 27% has been measured. Using the weak interaction perturbation analysis, we have found that the loss due to the scattering into the substrate modes is a dominator factor responsible for the measured low efficiency.
