Axis III : Innovative materials for Photonics

The fabrication of innovative photonic devices realizing compact optical functions is expected to have a major impact on societal domains such as health, the environment, displays, defense and telecommunications. This activity deals with the growth and the study of low-cost emerging materials to overcome technological or scientific challenges in order to fabricate new photonic components.
The FOTON laboratory, in particular through its technology platforms (NanoRennes and CCLO) works on the development of new materials and improves or implements new technological procedures enabling the fabrication of integrated optical circuits relying on emerging properties of these materials. Hybrid technologies are proposed to realize demonstrators making use of different materials thanks to the implementation of dedicated clean-room fabrication procedures.

The scientific activities of this research axis are concerned with the emergence of new materials at low cost or using innovative nanostructures for the development of new photonic devices with potential for large-scale integration and suitable for many applications. The aim of these activities is to study and synthesize specific materials, such as porous semiconductors, doped polymers, hybrid materials (perovskites, II-VI colloidal nanoscale platelets, clustomesogens). The growth of innovative III-V nanostructures by molecular beam epitaxy (MBE) is also investigated.

These emerging materials need to be synthesized and processed in various ways. Their potential applications cover a large variety of fields. Chalcogenide glasses, antimony-based III-V nanostructures, carbon nanotubes (CNTs) and polymers doped with chromophores are very promising with respect to their nonlinear properties. Hybrid materials such as perovskites, II-VI colloidal nanoplatelets, CNTs and clustomesogens offer interesting luminescence properties at low cost for applications such as displays or even as laser materials. Finally, nanostructured materials such as porous silica, porous Si or Ge, chalcogenide glasses or the use of III-V nanostructures in VCSELs are also promising materials for sensor applications, or the realization of advanced optical functions.
