ePIXfab is organizing a new Cross-Fertilization Workshop on High-Speed Optical Modulators, bringing together several European research projects working on related photonic technologies.
Cross-fertilization workshops are a recurring format organized by ePIXfab to connect researchers, engineers, and industry partners working on complementary aspects in photonics. These events bring together a specialized audience, enabling in-depth technical discussions that broaden perspectives on the technology and its potential applications while also fostering new collaborations between European partners. Previous editions have focused on topics such as Heterogeneous Integration and Applications in Quantum Photonics.
This new edition focuses on high-speed optical modulators, a key enabling technology in integrated photonics. The workshop will explore developments and challenges across the entire technology chain, including fabrication, integration, characterization, packaging, and applications. The event is co-organized by several EU-funded projects active in this area including PHORMIC, PhotonixFAB, DYNAMOS, PATTERN, STARLIGHT, LOLIPOP, and SPRINTER.
The workshop will feature a two-day technical program covering the full ecosystem of high-speed optical modulator technologies. Key topics include:
This workshop is intended for professionals and researchers involved in integrated photonics and high-speed optical systems, including:
The event will bring together over 100 participants from both academia and industry, creating a focused environment for technical exchange and networking.
Registration will open soon and will be announced on the ePIXfab website and LinkedIn channels. Participants will be able to register through Eventbrite, where ticket options and further event details will be available.
Due to the targeted nature of the workshop and venue capacity, places will be limited, and early registration is recommended. An option to participate online is also possible.
