The function of high-power silicon photonics modules
High-power silicon photonics modules enable ultra-fast, energy-efficient optical communication by integrating modulators, waveguides, and photodetectors on a silicon platform, supporting high-bandwidth data transfer in AI, cloud, and data center networks.
Core Functionality
High-power silicon photonics modules combine silicon-based semiconductor manufacturing with photonic components to transmit and process data at the speed of light while leveraging CMOS scalability . These modules integrate photonic integrated circuits (PICs) on silicon-on-insulator (SOI) substrates, including waveguides, modulators, and photodetectors, enabling compact, low-loss optical routing . Optical modulators, such as Mach–Zehnder interferometers and micro-ring resonators, convert electrical signals into optical signals at high speeds, supporting data rates of 100 Gb/s and beyond . For light emission, silicon photonics often incorporates III–V materials like InP or GaAs, while germanium photodetectors handle optical-to-electrical conversion .
