Impact of carbon-ion implantation on the nonlinear optical susceptibility of LiNbO.

In this work we study the impact of ion implantation on the nonlinear optical properties in MgO:LiNbO via confocal second-harmonic microscopy. In detail, we spatially characterize the nonlinear susceptibility in carbon-ion implanted lithium niobate planar waveguides for different implantation energies and fluences, as well as the effect of annealing. In a further step, a computational simulation is used to calculate the implantation range of carbon-ions and the corresponding defect density distribution.
