Abstract
A composite optical waveguide structure is proposed which is calculate d firstly to extend the operating range of second-harmonic generation to shorter wavelengths, and secondly to improve its conversion efficie ncy. In an example using LiNbO3 it is shown that second-harmonic outpu t is feasible down to 435 nm and the overall efficiency is doubled rel ative to mode matching in a simple waveguide structure.
