In recent years, silicon photonics technology has developed rapidly and has important application potential in the fields of optical interconnection, optical computing, and optical sensing. However, due to the limitations of silicon materials, there are still huge difficulties in the realization of active devices in pure silicon systems. In recent years, two-dimensional materials have received widespread attention for their unique and excellent optoelectronic properties, and are compatible in process, providing an attractive solution for silicon-based active devices. Recently, Professor Dai Daozin’s team was invited by "Nanophotonics" to write a long review paper on the topic of "Hybrid silicon photonic devices with two-dimensional materials", focusing on the discussion and analysis of silicon-two-dimensional material photodetectors and optical switches/optical modulations. The development status and existing problems of the device, and prospects for its future development.
