簡介目錄

預計到 2026 年，矽光電半導體市場規模將達到 34 億美元，到 2032 年將達到 124.5 億美元。這意味著從 2026 年到 2032 年的複合年成長率將達到 24.1%。

矽光電正成為在處理器、交換器、加速器和網路基礎設施之間傳輸大量資料的關鍵半導體技術。該技術將光學功能整合到矽相容晶圓上，從而可以在單一光子積體電路 (PIC) 中整合波導管、調製器、檢測器、連接複用器、整合器和熱控元件。這種方法使製造商能夠利用半導體製造和封裝基礎設施來擴大光整合規模和產量。

資料通訊和電訊仍然是最大的商業應用領域。矽光電（PIC）應用於400G、800G以及新興的1.6T光系統。然而，隨著光轉換技術在運算和網路領域逐漸接近矽基元件，市場正進入一個更廣泛的發展階段。近封裝光學元件、共封裝光引擎以及用於處理器和加速器的光I/O晶片正成為關鍵的成長領域。這些架構縮短了高速電氣連接的長度，並滿足了人工智慧基礎設施日益成長的功率和頻寬需求。

此外，晶圓代工產能的擴張也對市場產生了正面影響。半導體製造商正從矽光電的專業化生產轉向大規模生產。這為無晶圓廠光電公司創造了機會，使其能夠利用經過認證的製程平台，而無需自建晶圓廠。同時，先進的光電封裝、雷射整合、晶圓級測試以及「已知良品晶片（NGD）」認證對於商業部署而言也變得越來越重要。

市場促進因素

人工智慧網路使光轉換更接近計算。

人工智慧運算的快速發展顯著提升了加速器、交換器、記憶體和處理系統之間的頻寬需求。隨著電氣連接遍布基板和機架，確保功耗和訊號完整性成為更大的挑戰。
利用矽光電技術，可以在非常靠近處理器和網路專用積體電路（ASIC）的位置將電訊號轉換為光訊號。這縮短了高速串列器/解串器（SerDes）的電連接長度，從而提高了頻寬密度和電源效率。
因此，光I/O晶片和共封裝光引擎正成為市場擴張的關鍵領域。英特爾的光運算互連（OCI）、格羅方德的SCALE平台以及Marvell的1.6T光引擎都反映了光連接與處理器整合發展的趨勢。

鑄造廠的生產能力正在向大規模生產轉變。

商業晶圓代工廠產能的保障正推動矽光電轉型為可擴展半導體市場。 Tower Semiconductor已獲得價值13億美元的矽光電銷售契約，預計2027年客戶晶圓訂單將進一步成長。
GlobalFoundries也正在拓展其在矽光電和先進封裝領域的能力。這些進步使無光電半導體公司能夠利用現有的晶圓加工基礎設施，從而減少對自建製造設施的需求。
擴大代工廠產能可以簡化客戶更換供應商的流程，並降低認證門檻。製程設計套件、裝置庫、晶圓良率、測試和封裝能力，與光元件的性能一樣，正成為重要的競爭因素。

光纖通訊技術的發展速度不斷提高，這將導致可整合的光電數量增加。

隨著我們從400G和800G過渡到1.6T乃至未來的3.2T光系統，光通道數量和所需的整合密度都在增加。由於系統需要在緊湊的封裝內整合多個調變器、檢測器、波長通道和路由功能，矽光電的價值也因此進一步提升。
隨著頻寬的擴展，分波多工(WDM) 和整合被動光子功能的重要性也日益凸顯。這些技術進步使得光引擎中半導體含量不斷增加，同時在不相應增加封裝尺寸的情況下實現了高頻寬。

拓展資料通訊通訊以外的應用

雖然資料通訊仍然是主要的收入來源，但矽光電正在擴展到雷射雷達、光計算互連、光子量子計算、感測和其他光子應用領域。
在雷射雷達系統中，整合光子技術可用於頻率調製連續波（FMCW）架構。光子量子運算正在催生另一個新興應用領域。 Tower Semiconductor 與 Xanadu 的合作展示了半導體製造方法在光子量子處理器中的應用。
雖然這些應用領域的規模比資料通訊小，但它們擴大了潛在基本客群，並創造了進一步的開發和代工機會。

市場限制因素

雷射整合及對III-V族材料的要求

矽雖然是許多被動式和電光功能元件的理想平台，但它並非高效率的發光材料。因此，矽光電系統通常需要整合外部雷射或III-V族半導體材料。
這增加了製造流程的複雜性，並對供應鏈和包裝提出了更高的要求。雷射鑲嵌、黏合效率、溫度控管和可靠性都必須在生產規模上有效控制。
因此，整合不同半導體材料的需求可能會限制原本與矽相容的光電平台的簡易性。

光纖安裝和測試的複雜性

光子裝置需要精確的光纖鍵合和光學對準。這些製程比傳統的半導體封裝製程更為複雜。此外，晶圓級和晶片級光學測試也需要專門的設備和流程。
隨著市場大規模生產的推進，製造商需要改進自動化光學測試、光纖耦合和「諾克晶片（KGD）」認證。這些環節的良率下降會對光子半導體生產的經濟效益產生重大影響。

光學元件的高度整合可維護性

在共封裝光學元件中，光子元件與昂貴的開關或計算矽晶片緊密相鄰。這縮短了電氣互連的長度，提高了系統性能，但也帶來了維護方面的挑戰。
當高度整合封裝內的光子元件發生故障時，更換該光學元件可能比更換傳統的插入式光學模組更困難。這就需要在整合密度和可維護性之間做出權衡。

與 InP 和 VCSEL 平台的競爭

在那些對單一光學性能、成熟的製造流程或成本要求高於最大整合密度的應用中，磷化銦 (InP) 電吸收調製雷射和 VCSEL 技術仍然具有競爭力。
因此，矽光電要想在現有光學技術之外廣泛應用，就需要在頻寬、每位元功耗、整合密度、製造規模和整體系統經濟性方面展現出明顯的優勢。

促進因素
- AI光學I/O和CPO的實現
- 擴大代工廠矽光電生產能力
- 光學整合密度分別為 1.6T 和 3.2T
- 從資料通訊到LiDAR和量子技術的發展

簡介目錄

The Silicon Photonics Semiconductor Market is estimated at USD 3.40 billion in 2026 and is projected to reach USD 12.45 billion by 2032, representing a CAGR of 24.1% during 2026-2032.

Silicon photonics is becoming an important semiconductor technology for moving large volumes of data between processors, switches, accelerators, and network infrastructure. The technology integrates optical functions on silicon-compatible wafers and can combine waveguides, modulators, photodetectors, multiplexers, couplers, and thermal-control elements within a photonic integrated circuit. This approach allows manufacturers to use semiconductor fabrication and packaging infrastructure to increase optical integration and production scale.

Datacom and telecommunications remain the largest commercial applications. Silicon-photonics PICs are used in 400G, 800G, and emerging 1.6T optical systems. However, the market is entering a broader phase of development as optical conversion moves closer to compute and networking silicon. Near-package optics, co-packaged optical engines, and processor and accelerator optical-I/O chiplets are becoming important growth areas. These architectures reduce the length of high-speed electrical connections and address increasing power and bandwidth requirements in AI infrastructure.

The market is also benefiting from expanding foundry capacity. Semiconductor manufacturers are moving silicon photonics from specialist production toward higher-volume manufacturing. This creates opportunities for fabless photonic companies to access qualified process platforms without building their own wafer fabs. At the same time, advanced photonic packaging, laser integration, wafer-level testing, and known-good-die qualification are becoming increasingly important to commercial deployment.

Market Drivers

AI Networking Is Moving Optical Conversion Closer to Compute

The rapid expansion of AI computing is creating significant demand for higher bandwidth between accelerators, switches, memory, and processing systems. As electrical connections extend across boards and racks, power consumption and signal integrity become more challenging.
Silicon photonics can convert electrical signals into optical signals closer to processors and network ASICs. This reduces the length of high-speed electrical SerDes connections and can improve bandwidth density and power efficiency.
Optical-I/O chiplets and co-packaged optical engines are therefore becoming important areas of market expansion. Intel's Optical Compute Interconnect, GlobalFoundries' SCALE platform, and Marvell's 1.6T light engine demonstrate the movement toward processor-adjacent optical connectivity.

Foundry Capacity Is Moving Toward Commercial Production

The availability of merchant foundry capacity is supporting the transition of silicon photonics into a scalable semiconductor market. Tower Semiconductor has contracted USD 1.3 billion of silicon-photonics revenue for 2027 and has reported higher customer wafer commitments for 2028.
GlobalFoundries is also expanding its silicon-photonics and advanced-packaging capabilities. These developments allow fabless photonic semiconductor companies to use established wafer-processing infrastructure and reduce the need for captive manufacturing facilities.
Greater foundry capacity can also improve customer portability and reduce qualification barriers. Process design kits, device libraries, wafer yields, testing, and packaging capabilities are becoming important competitive factors alongside optical device performance.

Higher-Speed Optical Generations Increase Photonic Content

The transition from 400G and 800G toward 1.6T and future 3.2T optical systems is increasing the number of optical lanes and the required integration density. Silicon photonics becomes more valuable as systems require multiple modulators, detectors, wavelength channels, and routing functions in compact packages.
Higher bandwidth also increases the importance of wavelength-division multiplexing and integrated passive photonic functions. These developments increase the semiconductor content of optical engines while supporting higher bandwidth without proportional increases in package size.

Applications Are Expanding Beyond Datacom

Datacom remains the primary revenue source, but silicon photonics is expanding into LiDAR, optical compute interconnect, photonic quantum computing, sensing, and other photonic applications.
LiDAR systems can use integrated photonic functions for frequency-modulated continuous-wave architectures. Photonic quantum computing creates another emerging application area. Tower Semiconductor's collaboration with Xanadu demonstrates the use of semiconductor manufacturing approaches for photonic quantum processors.
These applications remain smaller than datacom, but they broaden the potential customer base and create additional development and foundry opportunities.

Market Restraints

Laser Integration and III-V Material Requirements

Silicon is an effective platform for many passive and electro-optic functions but is not an efficient light emitter. Silicon-photonics systems therefore often require external lasers or the integration of III-V semiconductor materials.
This increases manufacturing complexity and creates additional supply-chain and packaging requirements. Laser attachment, coupling efficiency, thermal management, and reliability must all be controlled at production scale.
The need to integrate different semiconductor materials can therefore limit the simplicity of an otherwise silicon-compatible photonic platform.

Fiber Attachment and Testing Complexity

Photonic devices require precise fiber attachment and optical alignment. These processes can be more complex than conventional electrical semiconductor packaging. Wafer-level and die-level optical testing also require specialized equipment and procedures.
As the market moves toward higher volumes, manufacturers need to improve automated optical testing, fiber coupling, and known-good-die qualification. Yield losses at these stages can significantly affect the economics of photonic semiconductor production.

Serviceability of Deeply Integrated Optics

Co-packaged optics place photonic components directly beside expensive switching or compute silicon. This can reduce electrical interconnect length and improve system performance, but it also creates serviceability challenges.
If a photonic component fails within a deeply integrated package, replacing the optical device may be more difficult than replacing a conventional pluggable optical module. This creates a trade-off between integration density and maintainability.

Competition from InP and VCSEL Platforms

Indium-phosphide electro-absorption-modulated lasers and VCSEL technologies remain competitive in applications where discrete optical performance, established manufacturing processes, or cost considerations are more important than maximum integration density.
Silicon photonics must therefore demonstrate clear advantages in bandwidth density, power per bit, integration, manufacturing scale, and total system economics to expand beyond established optical technologies.

Technology and Segment Insights

Semiconductor Product

Datacom and telecom silicon-photonics PICs represent the largest semiconductor revenue pool in 2026. These PICs are already manufactured at scale for optical transceivers and coherent optical systems. The segment captures the semiconductor-layer value of integrated modulators, detectors, and routing elements.
Optical-I/O chiplets and co-packaged photonic engines are the fastest-growing product category. Their current base is smaller, but they add photonic semiconductor content directly beside networking and compute silicon. Their growth is closely connected to AI scale-up and scale-out infrastructure.
Standalone modulators and photodetectors remain important for specialized optical systems. WDM and passive photonic ICs support dense optical lane aggregation and routing. Foundry wafer processing is another important value pool because every increase in fabless photonic production creates additional wafer-processing demand.
Semiconductor-level photonic packaging is also gaining importance. PIC and electronic integrated circuit integration, known-good-die testing, fiber interfaces, and advanced packaging are becoming essential as photonics moves closer to compute.

Integration Architecture

Pluggable-module PICs remain the established architecture because they fit existing optical-transceiver designs. However, near-package and on-board photonics are gaining relevance as electrical interconnect distances increase.
Co-packaged optical engines provide tighter integration between optical and electronic components. Processor and accelerator optical-I/O chiplets represent the most advanced architecture in the market. These solutions directly connect processors, accelerators, and memory-related systems through optical interfaces.

Application

Data center and AI networking represent the dominant application. Increasing accelerator bandwidth and network traffic are driving demand for higher-speed optical connectivity.
Telecommunications remains an established market, particularly for high-capacity optical networks. Optical compute interconnect is emerging as a significant growth opportunity as photonic connectivity moves into processor and accelerator architectures.
LiDAR and physical AI, photonic quantum computing, sensing, and other photonic applications provide additional opportunities. These applications are smaller today but can diversify market demand beyond conventional communications.

Manufacturing Model

Merchant silicon-photonics foundries are becoming increasingly important because they allow fabless companies to scale without building captive wafer fabs. Vertically integrated semiconductor manufacturers maintain control over process technology, photonic design, packaging, and system integration.
Fabless photonic semiconductor companies focus on device and architecture development while using external manufacturing. Foundry and advanced-packaging ecosystems combine wafer fabrication with specialized photonic assembly and testing.

Competitive differentiation is increasingly based on modulator bandwidth, photodiode performance, power consumption per bit, wavelength density, laser strategy, wafer yield, packaging repeatability, and access to high-volume foundry capacity. As photonic devices become more deeply integrated, known-good-die testing and electronic-photonic co-design will become increasingly important.
Recent market developments demonstrate the accelerating commercialization of the technology. Tower Semiconductor announced a major 300 mm silicon-photonics and SiGe capacity expansion in Japan in July 2026. In May 2026, the company disclosed USD 1.3 billion in contracted silicon-photonics revenue for 2027 and higher customer capacity commitments for 2028.

Marvell highlighted its 1.6T silicon-photonics light engine for high-bandwidth AI applications in March 2026. Tower Semiconductor and Xanadu expanded their collaboration on production-oriented silicon-photonics manufacturing for quantum hardware in February 2026.
These developments indicate that the market is moving from conventional optical-module integration toward semiconductor-level optical connectivity. The resulting opportunity extends beyond PIC sales to foundry processing, photonic packaging, optical-I/O chiplets, and integrated electronic-photonic platforms.

Conclusion

The Silicon Photonics Semiconductor Market is projected to grow from USD 3.40 billion in 2026 to USD 12.45 billion by 2032 at a CAGR of 24.1%. AI networking, higher optical bandwidth requirements, expanding foundry capacity, and the movement of optical conversion closer to compute are the main growth forces. Datacom and telecom PICs will remain the largest revenue pool, while optical-I/O chiplets and co-packaged photonic engines will expand at the fastest pace. North America will remain a major design and early-demand center, while Asia Pacific will remain critical for manufacturing and packaging. Laser integration, optical testing, packaging complexity, and competition from InP and VCSEL technologies will remain important constraints.
