Abstract
Phase-matched second-harmonic generation by mode conversion in a new w aveguide structure fabricated by the Langmuir-Blodgett (LB) technique is demonstrated. The nonlinear optically active part of the waveguide consists of two LB layers with opposite sign to the nonlinear optical coefficient d33. This configuration leads to a large improvement of th e overlap integral as compared to conventional waveguides. In first ex periments conversion efficiencies up to 1%W-1cm-2 have been obtained.
