Abstract
The invention relates to a process for manufacturing a monomode cylindrical optical waveguide made of a polymer and endowed with electrooptic properties. According to the invention, the manufacturing process comprises the following steps: PA0 producing a cylindrical core rod (11) by polymerization of a mixture comprising a core polymer and an electrooptically active organic substance, PA0 forming a first preform (10 ) by coating the core rod (11) by means of an optical cladding (12) formed by a cladding polymer, PA0 fitting said first preform (10) into a first jacket (20) constituted by a jacket polymer, PA0 producing a second preform (30) by drawing the first jacket (20), PA0 fitting the second preform (30) into a second jacket (40) made of a jacket polymer, PA0 producing means (41, 42, 43, 44) for positioning electrodes for excitation of the active substance, PA0 fiber drawing the second jacket (40) until the core diameter (d.sub.c) has the required dimension in order for the optical waveguide obtained to be monomode, PA0 producing said electrodes.
