Abstract

In this paper, a rigorous full-vectorial finite-element (FE)-based beam propagation method (BPM) has been implemented to study second-harmonic generation (SHG) in planar zinc oxide (ZnO) waveguides for the first time. It is shown here that the SHG output power is significantly improved when the waveguide structure is optimized. Furthermore, phase matching between the fundamental and second-harmonic modes, through the use of the quasi-phase matching technique, is discussed.
