Poled fiber, a method of fabricating the poled fiber, and a dispersion compensator

Abstract

The present invention includes a poled fiber using the second-order nonlinear optical phenomenon, a method of fabricating the poled fiber, and a dispersion compensator to compensate for the chromatic dispersion of an optical fiber. The method of fabricating the poled fiber according to the present invention comprises, a step of covering an etching-resistant material on the portions of the cladding excluding the portions to be grooved in the longitudinal direction of the fiber, a step of etching the bare portions of the cladding excluding the portions covered with the etching-resistant material, a step of evaporating electrodes on the etched portions, and a step of applying voltage to the evaporated electrodes. According to the fabrication method of the poled fibre as described above, along with the use of a general optical fibre instead of a special fiber, since the distance between electrodes around the core can be appropriately controlled, a high electro-optic coefficient can be induced to the poled fibre.
