For several years, our group has been working on the study of natural photonic structures. These structures have been developed in a different context than man-made structures – that of natural selection – and their study opens the way to new theoretical and experimental approaches and to a new vision of the development of an industrial product.
Indeed, when developing optical devices (such as photovoltaic or solar thermal panels, lighting surfaces, colored coatings, etc.), the main focus is primarily on the light flow management problem that needs to be optimized. But with such systems, it is often necessary to meet many other constraints. This requires knowledge and know-how in many fields of physics, other than optics or materials, (chemistry, engineering, thermics, tribology…) and often leads to complex solutions that strongly affect the main function. This approach is the opposite of that of nature. Natural structures are built on three fundamental principles:
- They are multifunctional
- Their architecture is complex and generally multi-scale
- They are developed from a very small number of components, and all these parameters are optimized.
Thus, the core of our work is the development of bio-inspired photonic and multifunctional structures. They are then oriented towards the transposition of natural approaches – both the concepts (disorder, multifunctionality…) and the structures themselves (Figure) – to the development of nanostructures for various purposes: renewable energy, mainly solar, color effects, detection structures, transparent or anti-reflection structures…

These works are therefore divided along three axes:
- Reproduction of natural structured surfaces by sol-gel and physical (PVD) methods.
- Modeling and Visualization of optical effects, characterization of disordered effects.
- Search for new structures and new effects on thermo chromic and hygrochromic structures, hydrophobic photonic structures, absorbing/emitting structures, anti-abrasive photonic structures, molecules detectors…
