Topic description

The subject concerns the fabrication of micro-structured photonic materials for telecommunication photonic circuit, quanttum technology and data storage archival. Glass turns out to be a material of choice thanks to its intrinsic transparency if one can locally control the optical properties in 3D (refractive index, absorption, emission) and this at different scales: on the micron scale corresponding to that of the wavelength, but also on few tens of nanometers. 2D/3D nano-structuring will allow developing artificial materials with new or enhanced properties necessary for integrated optics. It would open the way to “freeform” optical systems that will combine different functions in a single component. Recently, several research groups have demonstrated that Laser glass interaction using specially designed photosensitive materials is a promising approach for developing 3D structured optical components.

The research program will be conduct...
