Precise control of both material properties and device geometry of silicon photonics has enabled a multitude of exciting nonlinear optical devices in recent years. This topical review will highlight these recent advances in nonlinear silicon photonics achieved through material engineering, fabrication optimization, and device design; as well as the resulting diverse set of applications that have resulted. Some applications of interest include quantum information processing, neural-inspired optical computation, and precision metrology. Silicon materials including crystalline, poly-, and amorphous silicon, silicon nitride, silicon germanium, silicon-rich nitride, and silicon oxynitride will be highlighted.
