PhLAM is a Partner in the PhotonIA Project of the PEPR DIADEM Program

The additive glass synthesis technique using two-photon polymerization (TPP) enables the fabrication of optical components or integrated optical functions directly on chips or optical fibers. The spatial resolution of this process can reach ~30 nm, allowing the creation of objects that were previously impossible to produce with standard methods.

Over the past few years, PhLAM has developed strong expertise in this field, notably through the Equipex Add4P and the ANR 3D Glassens project.

Multiple parameters play a role in the TPP fabrication method (laser speed, power, type of photo-initiator, resin composition, etc.). The PhotonIA project, lasting 48 months (PEPR DIADEM) and involving the photonics team of the PhLAM laboratory – UMR 8523 as a partner, aims to build artificial intelligence models capable of predicting, for each specific optical function, the best recipe for 3D laser fabrication by optimizing the different manufacturing steps.

The PEPR DIADEM (Integrated Devices for Accelerating the Deployment of Emerging Materials) is one of the winners of the first wave of exploratory PEPR calls for projects. Funded by France 2030, it aims to accelerate the design and market deployment of high-performance and more sustainable materials, notably through the use of Artificial Intelligence.
