Silicon Photonics Test Equipment Market Size

The global silicon photonics test equipment market was valued at USD 610 million in 2025. The market is expected to grow from USD 730.2 million in 2026 to USD 1.4 billion in 2031 & USD 2 billion in 2035, at a CAGR of 12% during the forecast period according to the latest report published by Global Market Insights Inc.

Growth in the market is attributed to the rapid expansion of AI data centers requiring high-bandwidth optical interconnects, the rising commercialization of co-packaged optics technologies, increasing volume production of silicon photonic devices, accelerating telecom and data communication network upgrade programs, and growing complexity of next-generation photonic integrated circuits.

The silicon photonics test equipment market is driven, in the first instance, by the rapid deployment of hyperscale AI data centers and the structural shift toward silicon photonics-based optical interconnects for high-bandwidth, low-latency processor-to-processor communication. As data center operators scale AI compute clusters to support large model training and inference workloads, silicon photonic transceivers have become the technology of choice for energy-efficient, high-capacity data movement. The U.S. Department of Energy reports that data center electricity consumption in the U.S was 176 TWh in 2023, and is projected to reach 325–580 TWh by 2028, reinforcing the urgency around deploying energy-efficient optical interconnect solutions and the downstream need for precision test equipment to validate their performance at manufacturing scale.^{[1]U.S. Department of Energy, energy.gov}

Growth in the silicon photonics test equipment market is further supported by the accelerating commercialization of co-packaged optics - a packaging architecture that integrates optical engines directly onto switch or processor packages to eliminate electrical interconnect losses. Co-packaged optics enable aggregate data rates exceeding 3.2 Tb/s per package, a threshold that conventional pluggable transceivers cannot reach within accepted power envelopes. The U.S. Department of Energy's Advanced Research Projects Agency–Energy (ARPA-E) has established that next-generation data center optical interconnects must achieve sub-picojoule-per-bit energy efficiency to remain viable at exascale compute densities,^{[2]U.S. Department of Energy - Advanced Research Projects Agency–Energy (ARPA-E), arpa-e.energy.gov} a performance benchmark that drives stringent electro-optical characterization requirements for precision test equipment across wafer, die, and module test insertions in co-packaged optics production lines.

The silicon photonics test equipment market increased steadily from USD 340 million in 2022 and reached USD 409.7 million in 2024, driven by the AI infrastructure buildout, co-packaged optics commercialization, volume photonic device production, telecom network modernization, and photonic integrated circuit complexity growth, the market is positioned for sustained double-digit expansion through 2035.

Silicon Photonics Test Equipment Market Analysis

Based on test insertion type, the silicon photonics test equipment market is segmented into insertion 1 - wafer level test , insertion 2 - double-sided opto-electronic (O-E) test and insertion 3 - singulated die test,

• The insertion 1- wafer level test segment led the market in 2025, holding a 39.5% share. This dominance reflects its critical role in early-stage validation of silicon photonics devices before wafer dicing, enabling identification of defects and performance deviations at the most cost-efficient point in the manufacturing flow. Wafer level testing-encompassing optical characterization, electrical probing, and uniformity assessment across full wafers-serves as the first comprehensive quality gate in silicon photonics production. Its demand is strongly reinforced by the scaling of high-volume manufacturing and co-packaged optics ecosystems, where early defect detection significantly reduces downstream packaging losses and improves overall yield efficiency.
• The insertion 2 - double-sided opto-electronic (O-E) test segment is anticipated to grow at a CAGR of 15.4% over the forecast period. Growth is driven by the increasing production of hybrid-bonded silicon photonic wafers, where electrical integrated circuits are bonded directly to photonic wafers, requiring simultaneous electro-optical test access from both wafer surfaces. Key demand areas include co-packaged optics volume manufacturing and advanced photonic AI accelerator device production. The double-sided test capability addresses a fundamental limitation of conventional single-sided probing, enabling full functional verification of hybrid-bonded PIC/EIC wafers in a single production-floor operation - accelerating throughput and reducing per-device test cost in high-volume environments.

• The probe cards & optical interface assemblies segment led the silicon photonics test equipment market in 2025 was valued USD 154.9 million due to its universal deployment across all test insertion stages - from wafer-level probing to singulated die and module-level optical access. Probe cards and optical interface assemblies serve as the physical coupling point between test instruments and photonic devices, making them a consumable and recurring revenue element within every silicon photonics test cell. Their dominance by share reflects both the broad deployment base across research and production environments and the relatively high replacement frequency driven by optical coupling degradation over operational cycles in automated probing systems.
• The automated test equipment (ATE) platforms segment is anticipated to grow at a CAGR of 14.6% over the forecast period. Growth is driven by the transition of silicon photonics testing from engineering-grade bench instruments to production-grade ATE systems capable of integrating photonic and electrical characterization within a single, programmable test environment. Key demand is emerging from co-packaged optics manufacturers and silicon photonics foundries scaling from prototype production to high-volume manufacturing, where ATE platforms provide the throughput, software integration, and production data management capabilities essential for yield improvement and process monitoring at scale.
