Abstract
The present invention relates to the fabrication of an optical device; and, more particularly to an electrode for fabricating periodically poled optical fibers and a fabrication method of periodically poled optical fibers using the electrode. To fabricate periodically poled optical fibers for improving the effect of three wave mixing in accordance with the second-order nonlinear optical phenomenon, the periodically poled optical fibers of the present invention is formed by using one or more electrodes with holes or grooves for a period satisfying the quasi phase matching condition between light waves in use. Also, using the electrodes described above, one or more holes or one or more grooves are formed on the surface of the optical fiber around the core in its length direction, and thereby make an optical fiber poled periodically.
