论文摘要
我们从理论上和实验研究II型第二次谐波生成中，在III-V-on-un-un-un-n-n-n-n-n-n-n-n-n-n-n-n-V-on-n-n-n-V-on丝网波导中。我们表明，传播方向起着至关重要的作用，并且可以利用纵向场成分来进行稳健有效的转换。我们预测，对于类似的波导尺寸，最大理论转换大于I型第二次谐波生成，并达到12％/w的实验转换效率，受传播损失的限制。
We theoretically and experimentally investigate type II second harmonic generation in III-V-on-insulator wire waveguides. We show that the propagation direction plays a crucial role and that longitudinal field components can be leveraged for robust and efficient conversion. We predict that the maximum theoretical conversion is larger than that of type I second harmonic generation for similar waveguide dimensions and reach an experimental conversion efficiency of 12 %/W, limited by the propagation loss.
