Voltage is applied between electrodes (14a, 14b) under UV irradiation to perform a UV excitation poling, thereby producing microcrystal particles at a core unit (10a). Accordingly, second-order optical nonlinearity is developed at the core unit ( 10a ) of an optical fiber ( 10 ) . Under a high-temperature condition, a second-order optical nonlinearity can be imparted by a comparatively low-voltage UV excitation poling when a second-order optical nonlinearity decreases.

Une tension est appliquée entre des électrodes (14a, 14b) sous rayonnement U.V. afin d'effectuer une polarisation d'excitation U.V., produisant ainsi des particules microcristallines dans une unité de coeur (10a). Par conséquent, une non linéarité optique de second ordre est développée au niveau de l'unité de coeur (10a) d'une fibre optique (10). Sous haute température, une non linéarité optique de second ordre peut être conférée par une polarisation d'excitation U.V. comparativement de basse tension lorsqu'une non linéarité optique de second ordre diminue.
