Abstract
An optical fiber for producing energy-dissipative and wavelength—selective filters is presented. The fiber includes a core and a cladding that are photosensitive to radiation and have a periodic perturbation of the refractive index. The periodic perturbation defines at least one Bragg grating with lines tilted with respect to the axis of the fiber. The refractive index difference between the core and the cladding is less than 3×10−3.
