Graphene and other two-dimensional materials have recently emerged as promising candidates for next-generation,high-performance photonics.In this paper,the progress of research into photodetectors and other electro-optical devices based on graphene integrated silicon photonics is briefly reviewed.We discuss the performance metrics,photo-response mechanisms,and experimental results of the latest graphene photodetectors integrated with silicon photonics.We also lay out the unavoidable performance trade-offs in meeting the requirements of various applications.In addition,we describe other opto-electronic devices based on this idea.Integrating two-dimensional materials with a silicon platform provides new opportunities in advanced integrated photonics.
