The development of silicon-on-insulator (SOI) waveguides has led to spectacular progress in silicon photonics. While many milestones have already been passed, there is nevertheless a very active research community exploring new directions.
One such direction is that of silicon-based photonics, which involves the integration of the SOI platform with non-silicon materials. The goal is to develop heterostructure devices that provide improved performance and new functionality, for example, in on-chip detectors. Kapser and Yu’s book begins with useful introductory chapters on conventional silicon photonics and then provides an up-to-date account of the status of the research field, focusing especially on the integration of Ge and GeSn devices with silicon-based platforms.
