VTT and PIXEurope Collaboration: A New Era in Photonics Innovation

VTT Technical Research Centre of Finland has announced its strategic partnership with PIXEurope, a pioneering European pilot line dedicated to Photonic Integrated Circuits (PICs). This collaboration marks a significant step towards advancing photonics technology in Europe, engaging in critical applications such as 6G telecommunications, artificial intelligence (AI), and advanced imaging and sensing technologies.

What is PIXEurope?

PIXEurope is an ambitious initiative that falls under the umbrella of the European Chips Act, aimed at bolstering the region's capabilities in the semiconductor and photonic sectors. With a substantial investment of EUR 400 million, the project aspires to develop and pilot cutting-edge integrated photonic chips in Europe. These efforts are crucial for industries that are increasingly dependent on high-performance and energy-efficient components.

The initiative is spearheaded by the Institute of Photonic Sciences (ICFO) based in Spain, bringing together various PIC technologies that cater to different strengths. This comprehensive pilot line is the first of its kind in Europe, aiming to create an open-access ecosystem for photonic integrated circuits, bridging the gap between multiple cutting-edge technologies ranging from ultraviolet to mid-infrared wavelengths.

VTT's Role in PIXEurope

VTT contributes to this expansive project by providing its in-depth expertise in thick silicon-on-insulator (SOI) technology. According to Timo Aalto, Research Team Leader at VTT, their existing thick-SOI PIC platform is designed to offer an unparalleled blend of low optical losses, dense integration, and a wide range of optical wavelengths. VTT is also planning to invest in new processing equipment that will enhance the fabrication capabilities in their Micronova cleanroom. This improvement targets the resolution of optical waveguide structures, which are vital for guiding light in PIC applications.

By advancing bold designs and innovative constructions, VTT's contributions will lower manufacturing costs and open the door to fresh applications across various sectors, further positioning Europe as a leader in photonics technology.

The Future of Photonics in Europe

The opportunity to utilize available technologies through Process Design Kits (PDKs) enables users and collaborators to innovate by integrating multiple functionalities into a single chip. This not only streamlines production but also paves the way for groundbreaking applications in various fields, including biomedical devices and telecommunications.

As VTT also leads multiple work packages in this initiative, they play an essential role in the development of all monolithic PIC technologies, which serve as a foundation for integrating additional materials that enhance functionality. According to Piia Konstari, VTT Director of Microfabrication Services, their involvement in PIXEurope reinforces the center's commitment to fostering a united European photonics ecosystem and aligns with their strong presence in microelectronics pilot lines.

Conclusion

Overall, the partnership between VTT and PIXEurope signifies a pivotal move towards establishing Europe as a powerhouse in photonics technology. With results anticipated by 2030, the potential progress in this field can significantly impact various applications and industries over the next decade. As research continues and technologies evolve, the collaboration sets the stage for the next generation of integrated photonic circuits that will shape the future of technology.
