Abstract
The method for drawing a fiber with a textured surface comprises the following steps: —forming of a preform from which the fiber is to be drawn with a textured surface; —addition of an outer layer to the textured preform to preserve the shape of the texture of the preform surface during the drawing operation; —drawing of a fiber from the preform, whereby the fiber keeps the formed texture of the preform surface and —removing the additional outer layer to leave the original surface textured fiber exposed. The obtained fiber can be used as a mold to form a textured hollow channel in another material, as a surface coating and as a pressure detector.
