Data storage, writing, reading and transfer has become the main issue of the Internet of Connected Things. Today, 90 % of the information stored is stored on hard drive. Their future is assured provided that technology continues to offer massive capacity, increased transfer speeds and reasonable energy consumption. On some of these points, conventional technologies have shown their limit and reducing consumption during writing or increasing writing speed itself will go through a technological break. This project proposes an information storage disruption solution to enable technology to deliver increased writing speeds (by a factor of 1000) and reduced energy consumption. For this, it is proposed to use an optical solution using lasers capable of producing femtosecond pulses (10-15s). It is based on the demonstration that an information bit can be returned in a few picoseconds without magnetic field using a single femtosecond pulse. In this project, the optimisation of materials on the one hand and the integration of these materials into devices on the other hand should allow for further breakthroughs in the field.
