Abstract
Second harmonic generation in optical planar waveguides is the most promising mechanism for frequency doubling of laser emission since light can be highly confined to the nonlinear waveguide medium. However, this advantage is achievable only by precise phase matching between the fundamental wave and the doubled frequency wave, which is hard to control at the fabrication stage. Two tasks are addressed: a basic design for the layer thicknesses of a two-layer waveguide to achieve phase matching, and second, a multi-layer-waveguide design to achieve broadened phase matching bandwidth.
