Experience Summary 

6 years experience in fundamental and applied physics, specifically in the field of novel multimode optical fibres. Applications of theoretical wave chaos investigations to a highly multimode optical fibre : development of novel interesting properties for optical telecommunications. First experimental realisation of wave chaos in a multimode optical fibre, supported by numerical simulations to analyse the spatial properties of waves in such a chaotic system and to confirm a few theoretical predictions. As an application of these properties, design, numerical analysis and experimental study of an optimised double clad fibre amplifier. In parallel, 3 years as university tutor in electronics in the first two years of physics degree and one year as tutor in high engineering school.

Summary of achievement:

Research:

-Design of an experimental set up in optics to study the spatial properties of waves.

-Experience in image processing.

-Numerical program simulating the wave propagation along a waveguide with an arbitrary cross section.

-Numerical tools of statistical analysis for the calculation of distribution and correlation functions.

-Qualification in Quantum Chaos theory.

-Experience in fibre amplifiers and multimode fibre propagation.

-Design of a setup to measure the pump absorption in double clad fiber.

Collaborations:

-Collaboration with the applied optics group of the Institut de Recherche en Communications Optiques et Microondes in Limoges (France) for the conception of an optimised fibre amplifier.
 

-Collaboration with the coherent optic group of the Institut de Recherche en Communications Optiques et Microondes in Limoges (France) for the use of single mode fiber in spatial interferometry.
 
-Cooperation with Christian Miniatura of Laboratoire Ondes et Désordre in Valbonne-Sophia Antipolis (France).
