The development of Microstructured Optical Fibers (MOFs) is one of recent most innovative progress in the field of optical waveguides. These fibers present wavelength-scale structures (presence of tiny air holes in their cladding, see Fig.1) with high index contrast giving them unusual properties that can used to design new generation of sensors or transport media. Only few studies have been devoted to the study of the radiation response of this class of waveguides to radiations, only to steady state -rays [1,2]. In this work, we evaluate, for the first time to our knowledge, the response of silica-MOFs to a pulsed (35ns) X-ray irradiation that is representative of the harsh environment associated with the future facilities devoted to the study of the fusion by inertial confinement (LMJ, NIF).
