Original Article by SemiVision Research
Silicon photonics is emerging as a major technological trend. To truly understand silicon photonics or optical engines, it is essential to grasp how foundries design photonic integrated circuit (PIC) process design kits (PDKs) and process flows. Taiwan holds a strategic advantage in this area, with a robust supply chain that includes TSMC, UMC, ITRI, the Hon Hai Research Institute, and leading research institutions dedicated to advancing the silicon photonics industry.
On April 11, 2025, SEMI organized a dedicated forum on silicon photonics to explore its future development. The SemiVision team also participated in this important event. We are pleased to share that one of the key coupler suppliers, SURUGA SEIKI, referenced our research on the silicon photonics supply chain as well as our CoWoS Material Overview during the forum.
SemiVision Research will conduct an in-depth analysis of this forum and share our insights with readers, focusing on the development roadmap and future outlook of Taiwan’s silicon photonics industry.
Silicon Photonics Technology and Industry Trends: A Perspective from Taiwan’s Supply Chain
The Role of Silicon Photonics in AI: Taiwan’s Rising Advantage and Challenges
As artificial intelligence (AI) continues to advance, so does the need for faster, more efficient computing technologies. One of the key innovations enabling this leap forward is silicon photonics—a technology that integrates light-based communication into silicon chips. This technology is poised to be a crucial enabler for AI, particularly in data centers, high-performance computing, and machine learning. Companies like Nvidia are already showing a highly optimistic outlook for silicon photonics, and with TSMC playing a pivotal role in its development, Taiwan’s silicon photonics industry is emerging as a global leader.
The Role of Silicon Photonics in AI
Silicon photonics involves the use of light to transmit data, which can dramatically increase data transmission speeds compared to traditional electrical interconnects. For AI applications, particularly in cloud computing and AI training, the need for faster and more energy-efficient data transfer is paramount. AI workloads demand immense computing power, and silicon photonics offers a solution by enabling ultra-fast data movement within servers and across data centers, all while reducing energy consumption.
In the world of AI, where real-time processing of massive amounts of data is necessary, silicon photonics provides a much-needed breakthrough. Optical data transmission can bypass the bottlenecks associated with electrical wiring, drastically increasing bandwidth and minimizing latency. This is especially important for AI training in deep learning models, where the transfer of data between processors must occur without delays that could slow down computations.
