Abstract: An optical fibre (1) is provided with a coating (2) which varies in thickness along its length, for use, for example, in optical fibre sensor systems, by applying layer of liquid coating material, and permitting surface tension to cause beading of the coating on the fibre before curing the coating material whereby to maintain the beaded structure.

Abstract: An optical fibre 1 includes a structure, for example as part of the fibre core structure or of a coating thereon, such that the deformation of the core structure (bending or pinching) required for optical power coupling between modes can be achieved simply by producing changes in the pressure pertaining across the fibre transversely to its length, such as by squeezing the fibre between two smooth surfaces or changing the fibre tension. The structure may include means extending helically or in a snake-like manner with respect to the length of the fibre. A helically extending means may be comprised by a helical rib (2) of the coating.
