It doesn’t matter where you run, what matters is the right direction

Optical communications field – the main application scenarios of silicon photonic chips

With the rapid development of artificial intelligence (AI) and machine learning (ML) applications, the demand is for components to exchange data quickly and consume as little power as possible while maintaining high computing density, especially in terms of short-distance connections between XPUs (CPU, GPU, and memory).

The AI computing era we are facing has the following characteristics:

Require faster network speeds – rapidly advancing towards 800G/1.6T
Require network products to have lower latency – improve computing efficiency, and increase the response speed and training speed of AI systems
Require network products to have lower power consumption – reduce energy consumption and develop sustainable AI computing power
Require higher reliability of system hardware and software – reduce failure rate, improve availability and user experience of AI services

In this context, traditional pluggable optical modules are already “stretched” in terms of cost performance and power consumption, while highly integrated high-speed silicon photonic chips have become a more superior option due to their obvious advantages in potential price reduction and power consumption. The market’s choice is the best proof. Silicon photonic modules have achieved partial commercial success, and the application of higher-speed silicon photonic modules will also increase significantly.

Silicon photonics is emerging as a promising technology compared to traditional methods. Silicon photonics can enable better communication between computing units such as CPUs and GPUs. Memory units can also be improved to increase the computing power and efficiency of AI applications.
