TSEM, positioned arsenic the ascendant subordinate successful AI photonics, operates the lone production-grade silicon photonics (SiPho) PDK globally, making it a captious spouse for large semiconductor companies specified as Lumentum (LITE), Coherent (COHR), Applied Optoelectronics (AAOI), Broadcom, and Marvell.

These firms trust connected TSEM to fabricate their photonics chips, arsenic nary different foundry possesses the capability. Despite TSEM’s smaller marketplace headdress of $18 cardinal compared to its customers—LITE astatine $50 billion—the company’s strategical value and near-monopoly successful the SiPho proviso concatenation make a important competitory moat.
