elecTRo-optically Actuated all-FIber Components for advanced endoscopic system – TRAFIC

Submission summary

Combining materials into fibers offers endless possibilities for creating devices with innovative functionalities. Complex architecture associating exotic glass compositions for nonlinear optics and metal(s) will bring decisive breakthroughs for tailoring optical and electrical wave propagation. The project TRAFIC (for ElecTRo-optically Actuated all-FIber Components for advanced endoscopic system) will tackle fundamental research aspects, through the look for an adapted combination of exotic glasses with metal composition and the investigation of complex nonlinear interactions (electric field-induced frequency conversion, symmetry breaking and dispersion modification). Mixing electrical and optical features in a unique guiding structure will further open new perspectives in terms of applied research, such as electric field-assisted multimodal imaging and detection employed for endoscopy. TRAFIC encompasses six Work Packages:
WP0 - Management and coordination
WP1 - Functional glasses development
WP2 - Multi-materials fiber processing
WP3 - Computational modeling
WP4 - Characterizations of hybrid optical/electrical (HybOE) fibers
WP5 - Development of fiber functionalities

TRAFIC aims (i) at bringing to the community an original class of oxide glasses which can be processed at temperatures compatible with other metallic materials and which can form a competing host device for Laser and for NLO applications and (ii) at developing new breakthroughs in the field of hybrid optical/electrical (HybOE) fibers that stem from altering the materials composition and arrangements (complex core structures, multiple electrodes). Combining several properties of such HybOE fibers, like electro-stimulation capabilities, electric field orientation, frequency mixing, ?(2) and ?(3) nonlinear susceptibilities, will be investigated. Furthermore, using these specific fibers, the main targeted application will be endoscopy. In particular, Electro-CARS (Coherent anti-Stokes Raman Scattering) micro-spectroscopy will be used to improve the quality of the diagnosis of biological/chemical samples, as well as to increase the sensitivity and the detection speed.
TRAFIC will merge together materials scientists, spectroscopists, physicists and Laser specialists in four research groups. Hence it will involve the adapted resources and expertise of (i) IRCER (University of Limoges) in tellurite glass materials and nonlinear (?(3)) properties, (ii) ICMCB (University of Bordeaux) in phosphate glass materials, Laser interaction and poling (?(2)), (iii) ICB (University of Bourgogne) in the engineering of exotic nonlinear glass fibers, and of (iv) XLIM (University of Limoges) in photonic, numerical modeling and in glass/fiber optical/electrical characterizations. The project relies on the excellence of the groups, and on the quality of the created consortium, which has already shown in the past its ability to work together. In addition, we have identified a company ready to support the TRAFIC project: KAMAX Inc. This is a Limoges-based start-up developing new polarimetric endoscopes for medical applications. The participation of KAMAX in the advisory board of TRAFIC will guide the team in defining the specifications of our devices and ensure the pertinence and feasibility of the applied aspects of the project. We are confident that innovation issuing from TRAFIC will provide new scientific and technological breakthroughs that will lead to a new level of fiber components for manipulating light, such as a novel generation of endoscopes upon technological transfer to KAMAX.
