The STARLight project brings together a consortium of leading industrial and academic partners to position Europe as a technology leader in 300mm silicon photonics (SiPho) technology by establishing a high-volume manufacturing line, developing leading-edge optical modules, and fostering a complete value chain. From now until 2028, STARLight aims to develop application-driven solutions focusing on key industry sectors such as datacenters, AI clusters, telecommunications, and automotive markets.
Led by STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, the STARLight consortium has been selected by the European Commission under the EU CHIPS Joint Undertaking initiative.
Silicon photonics is a preferred technology to support datacenters and AI clusters optical interconnects for scale-out and scale-up growth, as well as for other technologies such as LIDAR, space applications and AI photonic processors that require better energy-efficiency and power-efficient data transfer. It combines the high-yield manufacturing capabilities of CMOS silicon, commonly used in electronic circuits, with the benefits of photonics, which transmits data using light.
Addressing key challenges
The development of advanced Photonic Integrated Circuits (PICs) will tackle several challenges:
- High-speed modulation: creating highly efficient modulators capable of operating at speeds exceeding 200 Gbps per lane is a key focus
- Laser integration: developing efficient and reliable on-chip lasers is critical for integrated systems
- New materials: various advanced materials will be explored with actors like SOITEC, CEA-LETI, imec, UNIVERSITE PARIS-SACLAY, III-V LAB, LUMIPHASE, and integrated on a single innovative silicon photonics platform, such as Silicon-on-Insulator (SOI), Lithium Niobate (LNOI), and Barium Titanate (BTO)
- Packaging and integration: optimizing the packaging and integration of PICs with electronic circuits is essential to optimize signal integrity and minimize power consumption.
Applications-based innovations
1. Datacenters / Datacom
The STARLight project has an initial focus to build datacom demonstrators for datacenters, based on PIC100 technology, capable of handling up to 200Gb/s with key actors including ST, SICOYA and THALES. It will also develop prototypes for free-space optical transmission systems, designed for both space and terrestrial communication.
Additionally, the project will leverage the multidisciplinary experience of major contributors to shape the research effort towards a 400Gbps per lane optical demonstrator using new materials, targeting the next generation of pluggable optics.
2. Artificial Intelligence (AI)
The STARLight project aims to develop a cutting-edge photonic processor optimized for tensor operations, such as matrix vector multiplication and multiply-accumulate, with superior characteristics in terms of size, data processing speed, and energy consumption compared to existing technologies. Since neural networks – the core algorithms behind AI – rely heavily on tensor operations, enhancing their efficiency is critical for AI processing performance.
3. Telecommunication
The STARLight project plans to develop and showcase innovative silicon photonic devices specifically designed for the telecommunications industry. Ericsson will focus on two concepts to improve mobile network efficiency. The first involves the development of an integrated switch to enable optical offload within Radio Access Networks, allowing for more efficient handling of data traffic. The second concept explores Radio over Fiber technology to relocate power-intensive processing ASICs away from antenna units, thus providing enhanced capacity and savings in embodied CO2. Additionally, MBRYONICS will develop a free space to fiber interface at the reception of Free Space Optical (FSO) communication, which is a key element in the design of an optical communication system.
4. Automotive/ Sensing
The STARLight project will also demonstrate how it performs in sensing applications, and the close relationships of STEERLIGHT, a LiDAR sensors maker, with leading car manufacturers will help make this an industrial reality.
Within the project, THALES will develop sensors that accurately generate, distribute, detect, and process signals with intricate waveforms to demonstrate key functionalities. More broadly, the outcomes of this project are also intended to benefit the wider ecosystem of indoor and outdoor autonomous robot manufacturers.
