Photonics in France, with 80,000 jobs and 18.6 billion turnover, is a technology we unknowingly use every day

It is a promising sector in France with the potential to create 5,000 jobs in three years. But this area remains unknown. Photonics is the science of light. The only photonics chairs in France are the Centrallesupelec, Metz, Moselle.

Photonics is the science of light. We use it every day to watch television with our smartphones and computer screens, even in a supermarket or even to scan an item using fiber optics without knowing it. It is also found in intelligent vehicles that detect obstacles or to guide in military cases, missiles and night cameras.

However, this discipline remains unknown. Per CentraleSupelec, Metz, Moselle, the only chair of photonics in France. For Mark Sayamanna, the holder of this chair, if we know very little about this science, it is the fault of the scientists: ” Must be able to touch people’s hearts. Young people need to be motivated. I went to an engineering school. Young people talk a lot about artificial intelligence. Another way to think about photonics technology. However, this is the path to follow for environmental, ecological and energy change. “.

Photonics means 80,000 jobs in France, turnover 18.6 billion, 5,000 jobs in the next three years, a document of this sector.

The Metz Photonics Chair has created an educational binder with which all Moselle colleges are equipped. Its name: E-Lumi, a magic box for dozens of experiments in class. Among the most successful: How to hide a secret message for photonics? How to transmit music with light? How to make images disappear on any screen except yourself with polarization.

We are working on a guide light

In the Metz Photonics Chair, researchers are working on ways for the future: “This works light guide concern. Light, for you, it goes straight. We are working on a device that allows light to learn its path by itself without any electronic mechanical adjustment element. This is called all-optical information routing. That is the future. ” It can thus avoid or overcome an obstacle. We can also mention the use of laser to reduce its lifespan Waste Radioactive. For Marc Sciamanna, achieving our goal of reducing energy consumption is also essential. : “The best way to process information tomorrow is to use less electrical energy

We can keep information in the light

Transporting sound with light is already the case in our daily lives. Lucas Oliverio Metz is in the second year of Suplek’s thesis at Ecole Central, an expert in photonics. He explains to us:n This bench of practical work, light may be the carrier of information, in this case, here, sound, it may be music. If you pass a sheet through the laser, it irritates the beam and therefore stops the transmission of information and sound. This we find in telecommunication networks, in small size, with a laser with various optical effects. We can keep information in the light. We say that we modulate light with information. On fiber optic networks, this is exactly the type of installation that is available in an optimized and smaller version.

The Metz Photonics chair now sees things on a larger scale. He proposed a French Institute of Photonics that would soon become a reality dedicated to 3,000 m2 of photonics. Mark Sciamanna impatiently: “The idea was to create a space that would be suitable for everyone to discover the applications of photonics. To make them more visible we will move parts of our lab there. We plan to be the first photonic training center in France. The Institute project has been validated. We are embarking on a signing phase that will be one of the largest consortia, comprising four universities, support and innovation structures and about thirty companies in the Grand East region. The consortium should be set up in 2023 “.

The building should be completed by 2026. The Institute of Photonics will form a unified network of partners and sites (Metz Nancy-Troyes-Strasbourg-Mulhouse) connecting the Grand East region. In Europe, there are currently two Photonics Institutes in Germany and one in Spain. The future French Institute will also be cross-border. An agreement has already been signed in this regard.
