IndexBox Forecast Sees Data-Center Optics Supporting Semiconductor Laser Market Growth Through 2035
Редакция ЦОД:Главное
IndexBox has published a baseline outlook for the global semiconductor laser market through 2035, identifying rising data-center bandwidth requirements as a major demand driver. The forecast expects operators to progress from 400G optical modules toward 800G and 1.6T links as cloud and AI workloads expand.
- IndexBox's baseline case links semiconductor laser demand growth to expanding data-center bandwidth requirements.
- The forecast anticipates a transition from 400G optics toward 800G and 1.6T modules for data-center operators.
- The global market is projected to grow by about 8.5% annually from 2026 to 2035, reaching an index of 225 versus 100 in 2025.
- III-V wafer production capacity remains a potential supply-chain constraint under the forecast scenario.
- Asia-Pacific is identified by the source as the leading region for epitaxy and chip production.
IndexBox on 26 September 2026 released a review and baseline forecast for the global semiconductor laser market through 2035. The source characterises the market as entering a period of structural growth, with demand supported by data centers, telecommunications, automotive sensing and industrial processing.
For the data-center segment, IndexBox identifies bandwidth expansion driven by cloud and AI workloads as a principal source of demand. Its baseline scenario anticipates that data-center operators will move from 400G optical modules to 800G and 1.6T modules. The forecast implies that optical interconnect performance will remain a material consideration in the build-out of higher-capacity cloud and AI data-center networks.
IndexBox forecasts average annual market growth of about 8.5% between 2026 and 2035. It projects a market index of 225 by 2035, using 2025 as a base of 100. These figures are scenario-based projections rather than evidence of deployed capacity, signed procurement or completed investment.
The outlook highlights the role of high-speed and energy-efficient optical components, including VCSELs and edge-emitting lasers. It also identifies the Asia-Pacific region as dominant in epitaxy and chip production. For operators and infrastructure suppliers, the scenario could point to a greater share of network-related infrastructure spending being directed toward high-speed optics for intra-data-center and interconnect applications.
IndexBox's assumptions include no major supply disruptions beyond existing III-V wafer production-capacity constraints. Under that condition, suppliers able to meet requirements for energy efficiency, thermal stability and component qualification could be advantaged. Conversely, III-V wafer availability may remain a supply-chain bottleneck if constraints intensify.
For data-center infrastructure, the outlook points to growing dependence on high-speed, energy-efficient optical components, including VCSELs and edge-emitting lasers. If the baseline scenario materialises, component availability, thermal performance, reliability and access to specialised III-V wafers could become increasingly important to scaling AI and cloud network infrastructure.
