[Image] Shanghai, Xi’an, and Wuhan are betting on silicon photonic chips. In the “post-Moore era,” silicon photonic chips break through the traditional chip bottleneck with the advantages of photonic transmission, becoming a key support in fields such as AI computing power and autonomous driving. The three cities of Shanghai, Xi’an, and Wuhan have made precise layouts, forming distinctive development patterns in the silicon photonic track through event incubation, policy support, and technological breakthroughs, striving to seize the high ground of future industries.
