We report on CW second-harmonic generation in selectively oxidized AlGaAs multilayer waveguides. Frequency doubling of a 1.55 μm pump is observed with 2.8% W(-1) conversion efficiency and a maximum second-harmonic power around 0.3 mW. This is the strongest second-harmonic generation ever reported in semiconductor waveguides and an encouraging result toward integrated spontaneous parametric downconversion in the telecom range.
我们报告了在选择性氧化的 AlGaAs 多层波导中的连续波二次谐波产生。观察到 1.55 μm 泵浦的倍频转换效率为 2.8%W(-1)，最大二次谐波功率约为 0.3 mW。这是半导体波导中报道的最强的二次谐波产生，朝着电信波段集成自发参量下转换迈出了令人鼓舞的一步。
