Welcome !

FIMAP (Laboratory of Photonic Materials and Fiber Devices) is part of the Institute of Materials (IMX) at EPFL and pursue fundamental and applied research in the field of photonic devices and fiber technology. In particular, at the heart of our research is the development of innovative materials processing approaches, as well as novel device architectures, to realize micro- and nanostructure-based photonic devices to be deployed over unconventional substrates (large area, 1D, flexible, stretchable, etc..). Two major approaches are favored: one relies on innovative combinations of nano-imprinting strategies of polymer and sol-gel layers, with thin-film deposition techniques to realize multi-material nanostructured photonic systems over large area substrates. Another approach explores the emerging field of multi-material fibers where materials with a wide range of functionalities such as optic, optoelectronic or acoustic, can be integrated in precise nanostructured arrangements within thin, flexible and very long fiber substrates. While we study the fundamental aspects of the material processes at play in our different fabrication techniques, as well as the optical and optoelectronic properties of our devices, we also try to exploit our discoveries to propose new solutions in different fields of application such as energy harvesting, saving and storage, sensing and monitoring, health care and smart fabrics.
