➀ Jiu Feng Mountain Laboratory achieves a breakthrough in the field of silicon photonics integration by successfully lighting up a laser source integrated into a silicon-based chip, the first of its kind in China. This achievement uses a self-developed heterogeneous integration technology and completes the process of phosphorus indium laser diode integration within an 8-inch SOI wafer. This technology, known as 'chip light output,' replaces electrical signals with better-performing optical signals for transmission, which is a crucial means to revolutionize inter-chip signal data transmission. It aims to solve the issue of electrical signals approaching their physical limits. This breakthrough will have a revolutionary impact on data centers, computing centers, CPU/GPU chips, AI chips, and other fields. ➁ The technology is considered an ideal solution for breaking through the bottlenecks of power consumption, bandwidth, and delay in the post-Moore era. The key challenge lies in the development and integration of silicon-based chip-on-chip light sources. This technology is one of the few blank spots in China's optoelectronics field. ➂ The technology can effectively solve the problems of insufficient coupling efficiency, long alignment adjustment time, and insufficient alignment accuracy in traditional silicon photonics chips, breaking through the production bottleneck of high cost, large size, and difficulty in large-scale integration.
