The global optical computing market stands at one of the most consequential inflection points in the history of computing infrastructure. After decades of incremental evolution, the convergence of three independent but mutually reinforcing structural forces — the exponential bandwidth and energy demands of artificial intelligence, the progressive commercialisation of photonic quantum computing, and the maturation of silicon photonics manufacturing at semiconductor foundry scale — is driving a fundamental transition in how information is processed, transmitted, and stored at every level of the computing stack.

Optical computing, in its broadest commercial definition, encompasses the use of photons rather than electrons as the primary carrier of information for interconnection, processing, sensing, and quantum computation. The market spans five primary technology layers: photonic integrated circuits (PICs), which are the foundational hardware substrate manufactured at 300 mm wafer scale using CMOS-compatible processes; optical processors, which perform computation directly in the optical domain including matrix multiplication for AI inference; quantum optical computing, encompassing photonic quantum computers, quantum key distribution, quantum random number generation, and quantum sensing; optical interconnects and co-packaged optics, which replace copper electrical signalling with photonic links within and between chips, boards, and servers; and optical sensing, which applies PIC technology to LiDAR, biomedical diagnostics, inertial navigation, and environmental monitoring.

Growth is not driven by a single technology transition but by a cascading sequence of photonic adoption waves. The first and already underway wave is the AI-driven data centre bandwidth crisis: AI training clusters consuming hundreds of megawatts require optical interconnects at 800G and beyond simply because copper physics cannot deliver the required bandwidth at the distances and densities of modern GPU clusters. Co-packaged optics — integrating optical transceivers directly onto switch ASIC packages — is transitioning from pilot deployments to volume production between 2026 and 2028, representing a structural expansion of photonic content per data centre dollar that will grow the market at 50% CAGR through 2030.

The second wave is photonic AI processing: optical matrix multiplication engines perform the most computationally intensive AI operations — the linear algebra at the core of neural network inference — at the physical level in picoseconds, with energy consumption orders of magnitude below equivalent GPU operations. Companies including Lightmatter, Luminous Computing, and Optalysys are transitioning from research demonstrations to commercial deployments in the 2027–2031 period, targeting a winner-takes-most competition for the AI inference compute market that photonic architectures are structurally positioned to win on energy efficiency grounds as model sizes grow to trillions of parameters.

The third and highest-optionality wave is photonic quantum computing. In 2025, photonic hardware overtook superconducting systems as the largest quantum computing hardware sub-category by private capital raised, with PsiQuantum's $1 billion Series E, Xanadu's NASDAQ listing, and Photonic Inc.'s Microsoft-backed growth round collectively signalling decisive investor conviction that CMOS foundry-compatible photonic architectures represent the most credible path to million-qubit fault-tolerant quantum computation. 

The Global Optical Computing Market 2026–2036 is the most comprehensive and technically rigorous market intelligence report available on the global optical computing industry. Spanning 430 pages, 110 data tables, and 55 market forecast figures, the report provides quantitative market sizing, granular technology assessments, competitive intelligence across 98 company profiles, and ten-year forecasts for every major market segment, application area, material platform, and geographic region — all updated to reflect the decisive structural shifts of 2025 and 2026 including PsiQuantum's Nature-published Omega chipset breakthrough, the commercial ramp of 800G co-packaged optics at hyperscale data centres, and Xanadu's NASDAQ listing as the first publicly traded photonic quantum computing company.

The report begins with a detailed executive summary providing an immediate-use market snapshot, technology status assessment across nine major optical computing segments, and a four-table structured outlook covering short-term (2026–2028), medium-term (2029–2032), and long-term (2033–2036) projections. The introduction and key concepts section provides the foundational technical grounding required to interpret market dynamics correctly — covering the physics of optical computing, a detailed comparison of photonics versus electronics across every commercially relevant parameter, PIC architecture and component technology from waveguides and modulators through to heterogeneous integration and co-packaged optics, and a comprehensive treatment of quantum computing architectures including superconducting, trapped-ion, photonic, neutral atom, and topological qubit systems.

The materials and manufacturing section provides the most detailed publicly available assessment of PIC material platform economics and manufacturing trajectories, covering silicon-on-insulator, silicon nitride, indium phosphide, thin-film lithium niobate, barium titanate, gallium arsenide, and emerging platforms including diamond, aluminium nitride, and electro-optic polymers. Detailed fabrication method tables for each platform, heterogeneous integration technique assessments, wafer size scaling trajectories to 2036, and a benchmarked foundry capability matrix covering thirteen commercial PIC foundries provide the supply-side intelligence required for technology strategy and procurement decisions.

The optical computing technologies section covers four technology domains with depth and rigour not available in any competing publication. PIC architecture evolution is mapped across six generations from 2026 to 2036. Optical processor technologies — digital, analog AI/ML, neuromorphic, and Fourier optical — are assessed with competitive landscape tables covering every commercial-stage company. Quantum optical computing receives exhaustive treatment covering fusion-based quantum computing, GKP continuous-variable approaches, measurement-based computation, and the full quantum PIC component roadmap from single-photon sources through fast electro-optic switches to waveguide-integrated SNSPDs. Co-packaged optics and advanced packaging receives a dedicated section covering CPO architecture variants, the full CPO technology roadmap to 2036, and competitive analysis of all major CPO ecosystem participants.

The markets and applications section provides structured, quantitative treatment of seven end-market segments — data centres and HPC, telecommunications, quantum computing and communications, automotive and LiDAR, aerospace and defence, healthcare and biomedical, and industrial sensing and IoT — with individual market sizing tables for each segment forecasting to 2036. The market analysis and forecasts section provides the report's core quantitative deliverable: thirty forecast tables covering the global market by technology type, application, geography, PIC material platform, transceiver data rate, and quantum technology sub-segment, all presented consistently from 2026 to 2036 with CAGR calculations and sub-segment growth drivers.

Technology trends and future outlook, challenges and opportunities, and detailed sections on energy efficiency standards and material sustainability round out the strategic intelligence content. The report concludes with 93 company profiles organised across the full value chain, a 145-entry reference list with active hyperlinks, a comprehensive glossary of 80+ terms, and a complete list of abbreviations.
