Innovating the Future of Photonics

EDWATEC is a Swiss high-tech startup pioneering rare-earth ion-doped photonic integrated circuits for on-chip optical amplification. Established in 2023 as a spin-off from the Laboratory of Photonics and Quantum Measurements (LPQM) led by Prof. Tobias Kippenberg, EDWATEC operates as an integrated device manufacturer (IDM). The company is headquartered at EPFL Innovation Park, benefiting from direct access to EPFL’s advanced R&D and nanofabrication facilities at the Center of MicroNanoTechnology (CMi).

EDWATEC develops on-chip optical amplification using advanced erbium ion implantation into industry-grade silicon nitride waveguides (EDWAs). The process enables precise doping control and broadband gain across the C+L bands, fully compatible with silicon photonics foundry platforms. These amplifiers can be monolithically or hybridly integrated, offering scalable embedded gain for applications in optical transceivers, telecommunications, fiber sensing, and satellite communications.
