Job Description
Missions
The person's mission will be to study and develop multimode optical fiber endoscopes to perform multimodal imaging based on three different nonlinear effects: Coherent Raman Spectroscopy (CARS), second harmonic generation, and nonlinear fluorescence. The laser source used in the experiments will enable the implementation of a next-generation of supercontinuum in the multimode optical fibers.
Activity
This individual's work falls within the framework of a European ERC Synergy project, "Multiprobe," which aims to combine nonlinear endoscopic imaging with cold plasma treatment for colorectal cancers. The work will consist of studying the feasibility of such a system and demonstrating its effectiveness on organoids.
1) Assembly of an endoscopic system using vibration of a multimode optical fiber
2) Imaging of cancerous tissues using coherent Raman spectroscopy
3) Imaging of cancerous tissues using second-harmonic generation
4) Imaging of cancerous tissues by measuring tissue autofluorescence
5) Testing of gas-filled optical fibers
6) Measurement of nonlinear effects observed during optical pumping

Your Work Environment
This work will be carried out in Limoges at the XLIM UMR 7252 laboratory within the Photonics research group and the Biophotonics team. This position is offered as part of a European ERC Synergy 2025 project entitled "Multiprobe". Its aim is to develop a hollow multimode fiber optic endoscope for the identification and treatment of colorectal cancers.
Short periods of work (1-2 weeks) in Rome at the laboratory of Professor Stefan Wabnitz Sapienza may be undertaken.
