Tower Semiconductor: The Hidden AI Photonics Winner

Silicon photonics revenue more than doubled from $106 million in 2024 to $228 million in 2025 as hyperscaler AI demand accelerated optical networking adoption. Over 70% of new silicon photonics capacity through 2026 is already reserved through 2028, signaling strong structural demand visibility. The PH18 platform supports 100G, 400G, 800G, and emerging 1.6T optical transceivers used in next-generation AI data center networking.
