Tower Semiconductor committed approximately $3 billion to 300mm silicon photonics production in Japan, coinciding with UMC's announcement of its first 12-inch silicon photonics production wafers. This dual expansion by both an incumbent and a new entrant suggests a significant increase in anticipated demand for optical components driven by accelerating AI datacenter plans, including Korea's 8.4GW AI datacenter initiative.
Silicon photonics capacity is expanding rapidly across multiple foundries, indicating a structural increase in demand for AI networking components.
