Scientific Publications

Several novel areas for publication by the M-ENGINE’s project have already been identified (targeted journal): Ultra-low noise super-channel laser (Optica), On-chip amplification of a microresonator frequency comb (IEEE Access).

Conferences

Conferences are crucial to disseminating information to a diverse audience and for networking. Key conferences to be attended have been identified: Optical Fiber Communication Conf. (2024,2025,2026) and European Conference on Optical Communications (2024,2025,2026) Call: HORIZON-EIC-2023-TRANSITIONCHALLENGES-03 — EIC Transition Challenge: Chip-scale optical frequency combs.

Trade Shows

To get early feedback on the developments and results, trade shows will be attended regularly throughout the project. The feedback can guide the development process: Laser World of Photonics (2025, Munich), Photonics West (2024, 2025,2026), CLEO–Europe (2025).

Trade Associations

To disseminate and find potential new end users, the SME’s are active in trade associations such as the European Photonics Industry Consortium, European Quantum Industry Consortium, IEEE 400G ethernet standards committee, and Swiss Photonics Industry Assoc. Enlightra is planning to join the 6G Flagship.
