FIELD: production processes. ^ SUBSTANCE: invention refers to guided-wave and fibre optics, and can be used for fabrication of long-period fibre grids. Method of manufacturing corrugated optic fibres consists in the fact that fibre is submerged vertically into 5-30% solution of organic polymer in organic solvent and is vertically removed from solution; the procedure is repeated for 1-5 times, after that, fibre is dried. When fibre is removed vertically from solution, drops of solution flow down the fibre, and at the same time, solution is partially dried. Due to effects of self-organisation of drops, they are located at regular intervals along fibre. After fibre is completely dried, at the location of drops there formed are thickenings forming a corrugation. ^ EFFECT: simplifying manufacturing procedure of long-period fibre grids, enlarging range of materials for fibre grids. ^ 2 dwg |
