ABSTRACT:
A method of fabricating a poled fiber and a dispersion compensator. The method including patterning to cover an etching-resistant material on the body portions of the cladding and on one end or both ends of the optical fiber excluding the portions to be grooved in the longitudinal direction, etching the bare portions of the cladding excluding the portions covered with the etching-resistant material, evaporating electrodes on the etched portions and applying a voltage to the electrodes, and inducing periodic poling generating optical phenomenon of the second-order nonlinearity to the optical fiber through the patterned electrodes. The compensator including a periodic poled fiber to generate a phase conjugate wave of a difference frequency between a pump light and a signal light received from a fiber coupler, and a filter to pass the phase conjugate wave coming out from the periodic poled fiber.
