绝缘体上的AlGaAs（AlGaAs-OI）异质集成已被证明是一种高效的非线性光子学材料平台。当AlGaAs键合到二氧化硅上时，折射率有很大的差异，这导致波导具有强的模式限制和增强的非线性。这与低线性和非线性损耗相结合，使AlGaAs-OI成为探索非线性现象的理想平台。在这次演讲中，我们提出了最新的进展，设计，制造和测试的AlGaAs-OI波导的有效的二次谐波产生，超连续谱产生和光子对的创建。
The heterogeneous integration of AlGaAs-on-insulator (AlGaAs-OI) has proven to be a highly efficient material platform for nonlinear photonics. When AlGaAs is bonded to silica, there is a large difference in refractive index which results in waveguides with a strong modal confinement and enhanced nonlinearities. This, in combination with low linear and nonlinear losses, makes AlGaAs-OI an ideal platform for exploring nonlinear phenomena. In this talk we present recent progress on the design, fabrication and testing of AlGaAs-OI waveguides for efficient second harmonic generation, supercontinuum generation and the creation of photon pairs.
