综述了半导体波导中二阶非线性相位匹配的辅助技术。每种方法的突出点，与他们的优势和劣势方面的各种关键的应用程序进行了讨论。最后对这些技术的最新进展进行了综述。重点放在两种技术上，即通过利用量子阱混合的畴无序的准相位匹配，和使用布拉格反射波导的精确相位匹配。图中示出了（a）用于制造用于准相位匹配的光栅的离子注入掩模的光学显微镜图像，（B）离子注入掩模的扫描电子显微镜图像，（c）半导体脊形波导结构的扫描电子显微照片，以及（d）设计用于与准相位匹配结构集成的成组单片环形激光器的光学显微镜图像。
Techniques used to assist phase matching of second-order nonlinearities in semiconductor waveguides are reviewed. The salient points of each method are highlighted, with their strengths and weaknesses with regard to various key applications discussed. Recent progress in these techniques is also reviewed. Emphasis is placed on two techniques, namely quasi-phase matching via domain disordering utilizing quantum well intermixing, and exact phase matching using Bragg reflection waveguides.The figure shows (a) An optical microscope image of an ion implantation mask used to fabricate gratings used for quasiphase matching, (b) a scanning electron micrograph of an ion implantation mask, (c) a scanning electron micrograph of a semiconductor ridge waveguide structure, and (d) an optical microscope image of group monolithic ring lasers designed for integration with quasiphase matched structures.
