IQE and Tower Semiconductor announced a multi-year agreement for the supply of Indium Phosphide (InP) epiwafers that will support silicon photonics technologies aimed at AI-driven data center infrastructure. The agreement positions IQE as a strategic supplier for Tower’s silicon photonics roadmap, including optical connectivity solutions designed to address the growing bandwidth demands of large-scale AI clusters.
Under the agreement, IQE will supply InP epiwafers for several of Tower’s advanced silicon photonics platforms. The collaboration covers technologies targeting 200 Gbps-per-lane pluggable optical transceivers, development of next-generation 400 Gbps-per-lane optical modulators, and optical circuit switching technologies for future data center architectures. The contract includes minimum purchase commitments from Tower and reciprocal supply commitments from IQE, providing a framework for long-term production scaling.
The companies also resolved all outstanding intellectual property disputes through a separate agreement. As part of the settlement, Tower will grant IQE a worldwide, royalty-free license to porous silicon patents that were the subject of previous litigation, bringing all related legal actions to a close.
• Multi-year InP epiwafer supply agreement focused on AI data center optical connectivity
• Supports Tower’s silicon photonics roadmap for 200 Gbps/lane and future 400 Gbps/lane optical technologies
• Includes optical circuit switch development for large-scale AI infrastructure deployments
• Establishes minimum purchase and supply commitments between both companies
• Resolves all outstanding IP litigation through a royalty-free patent licensing agreement
• Strengthens Tower’s silicon photonics ecosystem and IQE’s position in hyperscale AI infrastructure supply chains
Jutta Meier, CEO of IQE, said: “This agreement reinforces IQE’s position within Tier 1 global hyperscale cloud and AI infrastructure markets. With decades of InP epitaxy expertise and established high-volume manufacturing capability, IQE is primed to support next-generation optical connectivity applications as they scale from innovation to commercial deployment.”
🌐 Analysis
While silicon photonics provides the manufacturing economics and integration advantages needed for volume deployment, InP remains critical for high-performance optical functions such as lasers and modulators. The roadmap discussed by IQE and Tower aligns with broader industry efforts to move beyond today’s 100 Gbps-per-lane architectures toward 200 Gbps and eventually 400 Gbps-per-lane optical engines for next-generation AI clusters.
The announcement also reinforces Tower Semiconductor’s growing position in silicon photonics foundry services. The company has expanded its silicon photonics offerings as hyperscalers, optical module vendors, and networking equipment suppliers seek alternatives to vertically integrated manufacturing models. The settlement of the porous silicon patent dispute removes a potential distraction and establishes a broader technology relationship between the companies as demand accelerates for optical connectivity, optical switching, and co-packaged photonics technologies supporting AI infrastructure.
