Guided tours

PHOTLINE (iXBlue, Photonic Solution Division)

3 December 11:05 - 12:00

Five-minute walk from FEMTO-ST - Visit limited to 2*20 people

Photline is a leading supplier of optical modulation solutions. The company masters the entire chain of LiNb03 modulators production from computer-assisted design to final characterization, through wafer processing.

Markets served by Photline are :
- Telecommunications
- Sensing and Instruments
- Defense and Aerospace industries
- The Research and Development community

FEMTO-ST (Franche-Comté Electronics, Mechanics, Thermics and Optics - Sciences and Technologies)

3 December 11:05 - 12:00 or 17:15 - 18:15

Founded in 2004, the FEMTO-ST Institute undertakes research in various scientific disciplines related to engineering, information technology and communication. Its objective is to master micro and nanotechnologies, to develop new devices and systems, to optimize their performance, to provide them with new functions and make them “smart”.
The Institute offers high-level multidisciplinary expertise in automatic control, acoustics, electronics, electrical and thermal engineering, computer science, applied mechanics, mechatronics, microsystems, nanotechnologies, optics and time & frequency.

Femtosecond Laser Micro machining

Machining, or ablation of matter in the femtosecond regime, in comparison to other machining regimes (picoseconds or nanosecond), allows for a better quality in the structuring of matter.

Many applications could be find in the fields of telecommunication, automobile, watchmaking or biomedical fields, as for examples:

• the manufacture of integrated components for the telecommunications of the future
• the inscription of motifs invisible to the naked eye  used in the struggle against counterfeiting

MOEMS and optics

MIMENTO clearoom facilities (part of the French network RENATECH)

Five-minute walk from FEMTO-ST - Visit limited to 2*20 people

The FEMTO-ST Institute has several leading edge technological platforms, including the MIMENTO Technology Center. Of national importance, MIMENTO is part of the french RENATECH network which groups together six major academic
technology centers. Unique in France, the Center includes:

• a “nanotechnology” module (nano-engraving, nano-lithography, etc.),
• a “micromanufacturing” module (3D structures, piezoelectric materials, hybrid micromechanics) and
• a pooled “R&D - Industrial innovation” module (industrial production line for piezoelectric micro-nano components).
