TAIPEI — Taiwan is betting that the next major revolution in the global chip industry may not be powered by electricity alone.
It could be powered by light.
As artificial intelligence drives an unprecedented demand for computing power, Taiwan is accelerating its push into silicon photonics and co-packaged optics, technologies designed to move massive amounts of data faster while using significantly less energy.
The move could give the world’s leading semiconductor hub another powerful role in the global AI race.
Taiwan’s Ministry of Economic Affairs says the nation is well-positioned to develop the emerging technology thanks to its deep semiconductor ecosystem and dominant role in advanced chip manufacturing, assembly and testing.
Why AI Is Creating a New Problem for the Chip Industry
The AI boom has created an enormous demand for faster chips.
But building faster processors is only part of the challenge.
Modern AI systems must also move huge volumes of data between processors, memory, servers and entire data centers.
That movement increasingly requires enormous amounts of power.
According to SEMI, the rapid expansion of AI computing has pushed data movement and energy consumption to the center of the technology industry’s next major challenge.
Traditional copper connections are also approaching physical limits in bandwidth, power efficiency and transmission distance.
That is where silicon photonics enters the picture.
Replacing Electrical Signals With Light
Silicon photonics uses light to transmit data instead of relying entirely on conventional electrical signals moving through copper connections.
The technology combines optical communications with semiconductor manufacturing processes.
The potential benefits are enormous:
- Faster data transmission
- Lower power consumption
- Less heat
- Greater bandwidth
- Longer transmission distances
Taiwan’s Ministry of Economic Affairs said optical transmission can reduce power consumption by roughly 30 to 50 percent compared with traditional approaches, while helping support faster AI and high-performance computing applications.
The Next Battleground: Co-Packaged Optics
One of the most closely watched technologies is co-packaged optics, commonly known as CPO.
Instead of keeping optical components separate from the main processing chip, CPO brings optical engines and electronic components much closer together in the same advanced package.
The goal is to reduce the distance data must travel.
That could significantly improve speed and energy efficiency.
SEMI says the technology is becoming increasingly important as AI systems expand beyond individual chips into massive server racks and data centers.
The industry is now moving toward system-level designs where the connection between chips can be just as important as the chips themselves.
Taiwan Has a Major Advantage
Taiwan is already one of the world’s most important semiconductor centers.
The Ministry of Economic Affairs says the island accounts for more than half of the global outsourced semiconductor assembly and testing market.
Taiwan also has a highly developed supply chain stretching from chip design and manufacturing to advanced packaging and testing.
That ecosystem could give Taiwan a significant advantage as silicon photonics moves toward large-scale commercialization.
The ministry has also pointed to Taiwan’s strength in advanced semiconductor manufacturing as a foundation for building a more self-reliant silicon photonics supply chain.
More Than 30 Major Companies Have Joined the Push
Taiwan is not relying on one company.
The country has been building an entire industry ecosystem around silicon photonics.
The Silicon Photonics Industry Alliance was established in 2024 with support from government, industry and research institutions.
The alliance includes more than 30 companies and organizations, including major technology players such as:
The goal is to solve critical technology challenges and strengthen Taiwan’s position across the silicon photonics supply chain.
TSMC Says Silicon Photonics Could Take Off
The technology received even more attention at SEMICON Taiwan 2026.
TSMC has said silicon photonics is expected to play a dominant role in the next phase of AI growth.
The company has also been advancing its own co-packaged optics technology, including its Compact Universal Photonic Engine platform.
TSMC vice president K.C. Hsu said the company was on track to move CPO technology toward production, while predicting silicon photonics would become an increasingly important platform for high-speed data connections.
The shift is being driven by one simple reality:
AI systems are becoming so large that conventional connections are struggling to keep up.
AI Data Centers Are Running Into a Power Wall
The growth of AI has created a new technological paradox.
The world can build increasingly powerful chips.
But moving data between those chips is becoming a major bottleneck.
SEMI warned that data movement in modern AI systems can consume enormous amounts of energy.
As AI infrastructure expands, the industry is being forced to rethink the entire architecture of computing systems.
The focus is no longer simply:
How fast is the chip?
The new question is:
How efficiently can the entire system move data?
That is why optical connections are increasingly being viewed as a critical part of the future of AI infrastructure.
Nvidia and the Global Race for Optical Computing
The global technology industry is also pouring more resources into optical technologies.
Taiwan’s Ministry of Economic Affairs noted that Nvidia had made a major investment in silicon photonics technology.
The push reflects growing expectations that future AI data centers will require more advanced optical interconnects.
Taiwanese companies are positioning themselves across different parts of the emerging market, including chip manufacturing, packaging, optical engines and network equipment.
SEMI Taiwan has described 2026 as a crucial year for the industry’s transition toward larger-scale deployment and commercialization.
Taiwan Is Moving From Research to Commercialization
For years, silicon photonics was viewed as a promising but difficult technology.
High costs, manufacturing challenges and questions about packaging slowed wider adoption.
That is now beginning to change.
Taiwanese companies are moving toward commercial products.
TSMC has continued advancing CPO technology.
Other companies across Taiwan’s semiconductor and electronics industries are developing optical components, packaging technologies and high-speed networking equipment.
Industry reports suggest that some Taiwanese companies have already entered volume production or are preparing for mass production of silicon photonics and CPO-related products.
The Battle Is No Longer Just About Making Smaller Chips
For decades, the semiconductor race focused heavily on making chips:
Smaller.
Faster.
More powerful.
The AI era is changing the equation.
The next generation of computing will also depend on:
How chips are packaged.
How memory is connected.
How data moves between processors.
And how much energy the entire system consumes.
Taiwan’s government and semiconductor industry are now investing heavily in those areas.
The Ministry of Economic Affairs has included silicon photonics among the key technologies being developed as part of Taiwan’s broader AI and semiconductor strategy.
Taiwan Wants to Control More of the Supply Chain
Taiwan’s ambition goes beyond manufacturing individual silicon photonics chips.
The larger goal is to build an ecosystem covering the entire technology chain.
That includes:
- Chip design
- Photonic components
- Electronic integration
- Advanced packaging
- Co-packaged optics
- Testing
- Optical communication modules
- High-volume manufacturing
SEMI says Taiwan’s silicon photonics ecosystem is increasingly connecting these technologies from design through production.
That could become a major advantage as global demand for AI infrastructure continues to surge.
A New ‘Silicon Shield’ for Taiwan?
Taiwan’s semiconductor industry has long been described as one of the island’s most important strategic strengths.
Now, policymakers and industry leaders are looking beyond traditional chip manufacturing.
Silicon photonics, advanced packaging, quantum technologies and AI infrastructure are increasingly being viewed as possible next-generation industries where Taiwan can build another technological advantage.
The strategy is clear:
Taiwan does not want to simply dominate today’s chip market.
It wants to help build the technology behind tomorrow’s AI systems.
The Race to Move AI at the Speed of Light
The next major AI breakthrough might not come from a faster processor alone.
It could come from solving the problem of how data moves.
As copper connections approach their limits, the technology industry is turning toward light.
Taiwan already dominates much of the global semiconductor supply chain.
Now it is trying to secure a leading position in the next layer of the AI revolution.
From advanced packaging to co-packaged optics, Taiwan is building the technology needed to connect the world’s increasingly powerful AI systems.
The competition has already begun.
And the next great technology race may no longer be about who can build the smallest chip.
It may be about who can move the most data — with the least power — at the speed of light.
