Abstract :
The efficiency of second-harmonic generation (SHG) induced by an externally applied periodic DC electric field was investigated. A finite element method was used to find the static electric field due to different interdigitated electrode structures. The resulting fields were used to calculate the overlap integrals which determine the SHG efficiency in an optical waveguide. The results show that there are reasonable differences in SHG efficiencies for the structures investigated
