This partnership establishes a critical design-to-fabrication workflow for InP-on-silicon photonic integrated circuits (PICs), directly addressing the need for optical interconnects in AI infrastructure. By integrating OpenLight's process design kit with Cadence EDA tools, Tower Semiconductor lowers the barrier to entry for developing active monolithic PICs that combine lasers, modulators, and amplifiers on a single chip. This advancement represents a significant step toward practical photonic solutions required to scale data center bandwidth and accelerate AI model training.
