With Moore's Law approaching to its end, the semiconductor industry starts to embrace the "More-than-Moore" concept that includes a diversity of new functionalities. Silicon photonics emerges as a promising option for this"More-than-Moore" concept. Just as integrating the inductor into CMOS platform in the late 1990s that enabled CMOS RF IC and created the mobile age, silicon photonics has the potential to revolutionize many new applications in the IoT and AI age. Nevertheless, silicon photonics faces challenges, such thermal sensitivity, on-chip laser, high efficiency coupling and so on. To solve these challenges, the co-design of photonics and microelectronics become essential.
