OBJECTIVES

The objective of this secondment is to design and manufacture complex photonic structures, integrated on chips or fibered in innovative materials, for photonics in complex environments. Conversely, optical approaches in complex environments will be used to propose new laser structuring methods.

Controlling wave transport in complex environments has been a highly multidisciplinary, active and dynamic field of research since the mid-1990s. The fundamental study of the mesoscopic aspects of wave propagation, particularly of light, has thus enabled the development of many applications in imaging and information processing. The usual approaches consist in shaping the wavefront, in a controlled way, in order to focus the light through a scattering medium (Fig. 1a), for example, or in manufacturing an artificial complex medium in such a way that the light spreads there according to a pre-established pattern (Fig. 1b).
Recent theoretical advances combined with technological advances in the manufacture of optical materials and the development of new structuring tools at the micro and nanometric scale allow new types of complex media to be explored. Among innovative media, structured materials with a non-linear optical response have shown increasing interest in recent years. They are still poorly studied in the field of photonics in complex environments and naturally have a strong application potential.
It is in this context that I developed within the team Ondes en Milieux Complexes of the Institut de Physique de Nice (INPHYNI) a research activity that focuses on photonics in complex and non-linear environments.

EXPECTED RESULTS

The benefits expected from this secondment are multiple. First of all, scientifically, the connection and exchanges between the communities of photonics in complex environments, the science of materials for optics and femtosecond laser structuring are very promising. From a fundamental point of view, achieving the objectives would constitute significant progress in each of the areas. In addition, each of these areas of photonics is likely to lead to developments in a variety of applications ranging from imaging to sensors and information processing.
On the other hand, new collaborations and new transdisciplinary research axes could be developed between INPHYNI, CELIA and COPL.
