VTT Collaborates with PIXEurope for Photonic Advancements
VTT has officially joined PIXEurope, a pioneering initiative aimed at establishing a robust ecosystem for Photonic Integrated Circuits (PICs) across Europe. This partnership brings VTT’s expertise in thick silicon-on-insulator (SOI) technology, poised to drive developments in next-gen applications such as 6G communication, artificial intelligence, mobility solutions, imaging, and sensing technologies.
The Vision Behind PIXEurope
PIXEurope is spearheaded by the Institute of Photonic Sciences (ICFO), committed to creating the first open access PIC ecosystem in Europe. This initiative is backed by significant investments, totaling approximately EUR 400 million, which focus on the development and fabrication processes of integrated photonic chips. The collaborative effort brings together various PIC technologies, showcasing diverse strengths and enabling innovative application solutions that cater to wavelengths from ultraviolet to mid-infrared.
Innovative Approaches in PIC Technology
Beyond the design and manufacturing of PICs, the pilot line integrates advanced functionalities pertaining to hybrid integration, packaging, and rigorous testing protocols. Users of this pilot line will benefit from Process Design Kits (PDKs), facilitating immediate application of developed technologies. By merging multiple functionalities into a single photonic chip, VTT and PIXEurope aim to lower manufacturing costs while fostering new opportunities, thus positioning Europe at the forefront of photonic technology advancement.
VTT’s Commitment to Technological Innovation
As Timo Aalto, Research Team Leader for VTT's Silicon Photonics Team, articulates, the contributions to PIXEurope involve leveraging VTT’s established Thick-SOI PIC technology while continuously enhancing its features. This technology provides an exceptional blend of low optical losses, high integration density, and a wide operational wavelength range, making it indispensable for current and future photonics applications.
Investment in Next-Generation Equipment
In alignment with the PIXEurope initiative, VTT is set to invest in cutting-edge equipment designed for processing SOI wafers in the Micronova cleanroom. This investment aims to refine the process of optical waveguide structure patterning and surface smoothness. Furthermore, it allows the integration of additional materials on SOI wafers, enabling features like rapid light modulation and detection, which are crucial for advanced photonic solutions.
The Road Ahead with PIXEurope
VTT is not just participating but actively leading a work package focusing on the development of monolithic PIC technologies in collaboration with multiple pilot line partners. These monolithic platforms will serve as the fundamental building blocks for the addition of more PIC materials in subsequent project phases. This commitment sends a robust signal of VTT's dedication to fostering a comprehensive and unified European photonics ecosystem.
Future Prospects in Photonics
Recognizing the strategic importance of this partnership, Piia Konstari, VTT’s Director of Microfabrication Services, expresses pride in contributing to PIXEurope through pioneering integrated photonics expertise. VTT’s role in this project complements its significant involvement in the Chips Joint Undertaking (JU) microelectronics pilot lines. The initiative promises to make a substantial impact, with expected final results projected for 2030, marking a crucial timeline for advancements in photonics technology.
