Abstract

Second harmonic generation (SHG) conversion efficiency in quasi-phasematched waveguides can be enhanced significantly by optimizing the linear properties of the guiding structure. We describe here a method for fast and accurate computation of the modal properties of continuous, periodically-poled, ferroelectric channel waveguides, and a multi-parameter optimization algorithm which we have used to increase normalized internal SHG conversion efficiency. We will show, with results from our simulations, how both mode confinement at the fundamental wavelength and overlap of the transverse modes at the fundamental and second harmonic wavelengths influence the SHG conversion efficiency. Finally, we will also present the theoretical phasematching characteristics of these designs, and discuss the possibility of high SHG conversion efficiency (2900% W(DOT)cm²) near non- critically phasematched regimes of operation.
