Silicon Photonics

Silicon photonics is a type of integrated photonics that utilizes silicon-based fabrication processes to create optical chips. Unlike traditional chips that rely on electrical signals for data transmission, silicon photonics uses photons as the medium, transmitting data through optical waveguides embedded within the chip. This technology enables functions that previously required large optical components to be integrated into compact chips, achieving faster and more energy-efficient data transmission.

As artificial intelligence continues to advance rapidly, data throughput is growing at an exponential rate. Traditional electronic components are increasingly limited by their transmission speed and energy consumption, becoming a bottleneck to overall system performance. As a result, silicon photonics is regarded as a key technology for next-generation data transmission—and even seen as a potential path to overcoming the limitations of Moore’s Law.

After all, no matter how powerful a computing chip is, if data cannot be transmitted in real time, the entire system will still be constrained by latency. Moreover, in long-distance or high-density transmission scenarios, large amounts of heat are generated, increasing cooling requirements, causing higher power consumption, and ultimately affecting system stability, hardware lifespan, and operating costs. This is where silicon photonics comes in—with its advantages in high speed, low latency, and low power consumption, it offers an ideal solution to these challenges.

Silicon photonics has demonstrated strong potential across various fields, particularly in upgrading data center infrastructure. By replacing traditional copper interconnects with high-speed optical links, it can effectively reduce transmission latency and energy consumption, thereby enhancing communication efficiency between servers and meeting the growing demands of artificial intelligence and high-performance computing in the future.

In addition, silicon photonics is rapidly expanding into emerging application areas such as automotive and healthcare. In the automotive sector, it can be used to develop high-sensitivity LiDAR modules, improving the accuracy of obstacle detection and environmental sensing—crucial elements in advancing autonomous driving technologies. In the medical field, silicon photonics’ superior sensing and data transmission capabilities show great promise for remote diagnostics, including physiological signal monitoring, real-time medical imaging analysis, and early disease detection—addressing high-precision needs in modern healthcare.
