Speech Title: Hybrid Optical-Electrical Switching Network Based on AWGR
Abstract:
Data centers and high-performance computing, serving as the physical carriers for the operation of information systems in various industries, are indispensable key infrastructures for societal operation. They also constitute an important part of China's national strategies for "east data, west computing" project and "New Infrastructure Construction." With the popularization and application of new technologies such as 5G, cloud computing and artificial intelligence, the demand for computing power is growing rapidly. In recent years, significant progress has been made in the development and application of large models represented by ChatGPT, further driving the demand for computing power. With the rapid development of data centers and high-performance computing centers, switching technology also needs to be upgraded and evolved to meet the requirements for high bandwidth, low latency, and low energy consumption in data transmission. Compared with traditional electrical switching technology, optical switching offers many advantages, including large bandwidth, low loss, strong anti-interference ability, and high-speed parallel transmission without crosstalk, making optical switching networks an important technological direction for communication development. This report will discuss hybrid optical-electrical switching networks based on AWGR (Arrayed Waveguide Grating Router), covering aspects such as tunable reconfigurable devices, low-latency flexible scheduling, and interconnect architecture design. It will detail the design and fabrication of flexible tunable optoelectronic integrated devices, nanosecond-level multi-dimensional optical interconnects, and real-time resource scheduling as key technologies.
