Um método de propagação de feixe tridimensional baseado em um esquema de elementos finitos é descrito para a análise de dispositivos de geração de segundos harmônicos. Para a análise de propagação do feixe de grande angular, a aproximação de Pade é aplicada ao operador diferencial ao longo da direção de propagação. Para evitar reflexões espúrias nas bordas da janela computacional, a condição de contorno transparente é introduzida. Resultados numéricos são mostrados para dispositivos de geração de segundo harmônico quase-fase usando LiNbO periodicamente invertido de domínio3 e LiTaO3 guias de onda. As influências da forma das regiões de domínio invertido e da largura de inversão nas eficiências de conversão são investigadas detalhadamente.

Abstract: A three-dimensional beam propagation method based on a finite element scheme is described for the analysis of second harmonic generation devices. For the wide-angle beam propagation analysis, the Pade approximation is applied to the differential operator along the propagation direction. In order to avoid spurious reflection from the computational windows edges, the transparent boundary condition is introduced. Numerical results are shown for quasi-phase matched second harmonic generation devices using periodically domain-inverted LiNbO3 and LiTaO3 waveguides. The influences of the shape of domain-inverted regions and the inversion width on the conversion efficiencies are investigated in detail.
