Description

Laboratoire Traitement du Signal et Instrumentation (TSI) is part of University Jean Monnet in Saint-Etienne, France. It comprises more than 50 co-workers all involved in optical technologies. It is one of the actors of the Pôle Optique Rhône-Alpes (PORA) located in Saint-Etienne. The group, which mostly contributes to NEMO’s objectives on microoptics, is the DOE group. Its ca 13 members all work on the development of diffraction gratings of wavelength scale period. A specific emphasis is placed on diffractive structures of the resonant type where the surface undulation or the index modulation is located within the field of a surface wave. The history of the DOE group, which is quite short, benefits from the large scientific potential accumulated for 30 years by one team of the Moscow General Physics Institute in the field of integrated optical gratings. The DOE group develops its own theoretical concepts and CAD tools, possesses the equipments for performing the submicron microstructuring of surfaces (grating exposure, mask transfer, Reactive Ion Beam etching, testing), and develops all possible applications of resonant gratings ranging from biochips to smart laser mirrors, most of the applications being undertaken in the form of industrial projects. The group is also investigating hybrid sol-gel materials and related technologies for low cost fabrication of surface corrugation. In this context, self-developing UV-curable materials are used to produce sub-micron period diffraction gratings and optical waveguides with a few processing steps.

After its recent move to new premises the TSI Laboratory has inherited a first class microstructuring infrastructure comprising three clean rooms, one for the running sol-gel platform of the PORA, one for the grating development work, and one for future industrial cooperation and start-up creation. A national programme is being prepared for reinforcing the microstructuring potential of the laboratory. The NEMO project is seen by the TSI lab as a timely opportunity to link with other European labs and to offer its accumulated potential and newly acquired facilities to European R&D as well as to industry.
