STMicroelectronics Enters Mass Production of 200Gbps Silicon Photonics Technology
Geneva, Monday, 9 March 2026.
STMicroelectronics announced today that its PIC100 silicon photonics platform has entered high-volume production, marking a pivotal moment in data center technology. The breakthrough 200Gbps per lane capability addresses surging AI infrastructure demands while dramatically improving power efficiency. Amazon Web Services is already partnering with ST to deploy this technology in their data centers. The company plans to quadruple production capacity by 2027 and has unveiled a roadmap targeting 400Gbps per lane using advanced through-silicon via technology.
Understanding Silicon Photonics Technology
This innovation falls squarely within the photonics sector of the semiconductor industry, representing a convergence of optical and electronic technologies on silicon substrates [GPT]. Silicon photonics technology combines optical and electronic components on a single chip, enabling light-based data transmission with unprecedented efficiency [1]. The PIC100 platform achieves remarkable technical specifications, featuring single-mode silicon waveguide loss down to 0.4 dB/cm and single-mode silicon nitride waveguide loss as low as 0.5 dB/cm across both O- and C-bands [1]. The technology incorporates Mach-Zehnder Modulator electro-optical bandwidth capability of 50 GHz and high-speed photodetectors up to 80 GHz, all integrated into a single 300mm stack [1].
Corporate Leadership and Manufacturing Strategy
STMicroelectronics, the company behind this breakthrough, operates its PIC100 manufacturing from its 300mm production lines in Crolles, France [2]. Remi El-Ouazzane, a key executive at STMicroelectronics, emphasized the strategic importance of this milestone, stating that the company is positioned to become a leader in the cloud optical interconnect market [2]. The technology platform was originally launched on February 20, 2025, with the 200Gbps per lane capability [1]. Now entering high-volume production as of March 9, 2026, ST has outlined ambitious expansion plans to quadruple PIC100 production capacity by 2027 [1][2].
Technical Benefits and Market Applications
The PIC100 technology addresses critical challenges in data center infrastructure, particularly the power consumption issues that have emerged from bandwidth upscaling in pluggable modules [1]. This silicon photonics approach offers significant advantages in power efficiency, bandwidth capabilities, and manufacturing scalability compared to traditional electronic solutions [GPT]. STMicroelectronics has also announced the BiCMOS B55X technology on March 8, 2026, which improves efficiency by 15% when integrated with PIC100 chips [1]. The platform supports ST customers who are ramping up 800 Gbps and 1.6 Tbps pluggable modules, demonstrating its relevance for next-generation data center requirements [1].
Future Roadmap and Industry Partnerships
STMicroelectronics has unveiled a concrete roadmap for PIC100-TSV technology using through-silicon via architecture to support denser modules and near- and co-packaged optics, with capabilities targeting 400 Gbps per lane [1]. The company is actively developing through-silicon-via modules and compact modulators specifically for GPU-to-X optical interconnection applications [1]. Amazon Web Services represents a significant early adopter, working with ST and a leading optical module provider to integrate PIC100 technology into their data centers [1]. El-Ouazzane highlighted the synergy between ST’s silicon photonics platform, BiCMOS technology, STM32 products, and advanced packaging capabilities as providing unique competitive advantages as the market evolves from traditional pluggables to near and co-packaged optics [2].
