The research progress of the silicon-based photonic integration in the world and the results of our group in recent years are reported in this paper, including exploration of design and improvement on process of the optical transceiver modules, Ⅲ-V/silicon lasers and other integrated photonics. The silicon photonics is predicted to have a great prospect in many fields due to its good compatibility with complementary metal oxide semiconductor technology. It is concluded that the trend of photonic integration on silicon substrate is toward high data rate, low power consumption and large integration density, and the silicon based photonic integration will become a main research subject of silicon photonics in the future.
