ABSTRACT:
The invention relates to an optical fibre including, over a part of its length, variations of refractive index disposed in plane, parallel and periodic strata, of period I, which are inclined at an angle .alpha. in relation to the axis of the fibre. The normal to the strata forms a non-zero angle with the axis of the fibre. The invention also relates to the application of the invention optical fibre as a selective extractor of flux, a light injector, a coupler, a sensor and a polarizer.
