Optical waveguide with shaped photosensitivity profile for production of structures with photoinduced modulation of the refractive index, preferably the Bragg gratings

摘要

The notification concerns a fibre with a photosensitivity profile containing a nanostructured core,consisting of at least two types of glass rods, with at least one type of glass rods mixed with german. The notification shall also cover the production of a filament lamp containing a photoinduced modulation of the refraction factor.Depending on the specific type of fibre, such fibre lines are used, inter alia. in laser generation and amplification techniques (active fibre lines) and/or in fibre sensors and telecommunications applications (passive fibre lines).
